Everyone always talks about these Giles pumps and how awesome they are, but what does he do that a DIY'er can't? Does anyone actually know exactly what he does to them? Please tell me what he does to justify the price!
:D
-
We can't tell ya, because he won't tell us :)
The price appears high, but its in line really with the market place.
Price a new (reman) pump with a core charge. Not just a re-seal.
So you get basicly a new pump with the added feature that it has been modified for performance. Is it better than what someone else can do with a rebuild and turned up fuel screw? Who knows? He is king of the mountain for now.
I would not mind seeing someone put together a pump for the same or less money and have head to head tests runs. Perhaps a well built 1.6 or 1.9 on a Dyno. Run it hard, Swap the IP, Run it hard again! That could be verrry interesting..... :twisted:
-
I was thinking about sending a pump to him, but I've found that didling with the LDA pin and the high speed throttle stop (governor screw?) i can put more fuel into my engine than it can handle (EGT wise) at 20 PSI booste.
So cough it up... Bosch certified pump rebuilds are $700 usd here in the states. What justifies the higher price?
Oh, BTW, he does not respond to Emails

There's an old joke about a guy with an engine that wouldn't run right... he took it to shop after shop and no one could get it to work.
Finally he takes it to "The Wizard"... the dude recommended by all the other shops in town. The Wizard pops the hood, listens carefully, and says "I can fix it for $1000". The owner is desperate at this point and says sure.
The Wizard goes back into his shop and comes out with a hammer. He reaches in to the engine compartment and taps the engine once. Instantly the engine begins to purr like a kitten. "That will be $1000" says the Wizard.
The owner is outraged !! "Are you kidding ??? You can't charge me $1000 for that... I demand an itemized bill"
No problem, says the Wizard:
Tapping with a hammer................$10.00
Knowing exactly where to tap......$990.00
-
Hahaha, good joke!
My Grandpa did something similar in his home fencer business. He normally had people drop off the fencers at the co-op and he'd have them delivered. This time he allowed a customer to come in because he was in a rush and needed the fencer back ASAP.
Grandpa fixes the fencer after about 2 minutes of troubleshooting and tells the customer how much it would be. The customer balks and grandpa takes the fencer back and desolders the fix :D
After the guy changed his mind Grandpa sent him on his way (repaired) and told him that he was paying for the experience/knowledge, not the $5 capacitor etc.

Anyone have any numbers (cc´s) from Giles?
I paid 1000 euros for custom 12mm pump here :roll: 200cc+@6000rpm
-
Giles' contact info: http://vwdiesel.net/phpBB/viewtopic.php?t=7397

Don't you guys know?
Giles makes black voodoo magic happen in that shop of his. He'll never tell any of you. Or me.

I think we could figure it out if we dug far enough. :D
-
You guy's gonna start killing chickens now? :shock:
While I am sure some people could reverse engineer the pump, This is how the man makes his living. He appears to be helpful on this site. No need to pee in his cornflakes. :wink:
-
the pumps are not magical, he probably do a couple modifications, but its not all that easy to tune a pump.
i saw several engine failure's and engine's who never ran just becouse some guys thought VE tuning is simple, its all very complicated. What do you choose, a engine failure or a GOOD modified pump :wink:
on this board i see you guys talkin like its all so easy, but after you think you know it all, you start realizing its all damn hard. Even with pumpdyno.
Guys, i'm not telling you to send your pump to Giles, i'm also the kind of man wich wanna tune it his own, but if you realy ask me the cheapest solution, go for a Gilespump. For VE pumps, dont think there is a DIY, if you know how long a BOSH-VE training takes you start understanding what i mean :wink:
Look it this way, if you go to a local tuner to chiptune your car you also dont know what he do, he also dont need to jusify his price.
Just my 2 cents, Benjamin
-
i think its great that giles is doing vw hot rod pumps for us
but im glad that "my guy" built me a pump for about 1/3 the price(parts included)
and ive never been in a giles equipped car, but if mine is 80% as good as his,im happy
mines been workin great for a couple of years now+no complaints here
awesome throttle response(almost too good!),good power+some room to turn it up a little more
if you are in a pinch,research locally+try to find a good "diesel pump guy" that you can talk to
even just a plain pump with a 12mm head will add alot of power to your car,even if it doesnt"have the correct advance curve+specificaly tuned with your vw in mind" like giles
most pump places that have a clue can probably convert a ve pump for around 6-800$$
-

Heh. There'll still be plenty of people who go to him regardless of whether or not someone can figer how to do what he does. This would just be for those of us who would rather spend our time than our money.
-
What he does that you a DIY'er can not do is put it on a calibrated test bench, and make accurate changes to both the timing curve, and the total advance, as well as the fueling vs rpm, and fueling vs boost. Not to mention all the other little bits of knowledge that he has picked up about what combination of parts works best that comes from building thousands of pumps. No pump building is not rocket science, but it is damn near rocket surgery.
Yup there are lots of people who can build pumps out there, but Gilles to this point is the only one I have come across that has taken a special interest in these pumps in specific, and made them custom to our needs. As far as the big power IDI's in North America, they are all powered by a Gilles pump, think that is a coincidence? Don't think that lots of us tried our own homemade performance pumps first before dropping a grand on pump? Only to go WOW, once we stepped up.
I'm sure you could take a Gilles pump to any half decent pump builder and they could replicate that specific pump, but could they do it for any cheaper??? And what about if you want something other then that pump. All of Gilles pumps are custom, that I know of, you tell him what you are planning on doing and he recommends what he thinks will work the best for that application, if you still have your heart set on another direction he will build the pump as best as he can to you specs I.e: 9mm heads or 14mm heads, cummins cam plates, tdi cam plates, or 1.9 cam plates, Twin turbo, single turbo, nitrous, race car, street car, no smoke, lots of smoke Ect...
-
You're paying for his years of R&D, experimentation with non-standard settings and figuring out how to make it run smoothly and more efficiently all around.
A DIY could start playing, but you'd also need some sort of test rig on the bench to help you understand what's happening properly, or an awful lot of swapping pumps in and out of their cars.
The price he provides for the "extra" tune isn't that much more on top of the rebuild price, only a couple hundred bones. And I know that also includes replacement parts, not just what you send him, so I don't think you're paying a lot extra to him for his additional time to put things together.
-
got my truck running with a Giles pump, runs good. Does he send the pump back fully tuned or at a 'base' setting? Can I make adjustments for more power or is it already tuned up? I dont want to mess with anything if he already tuned it on the bench.
-
have you actually seen the inside of all those bosch repair manuals?
they are about as thick as a phone book and chock full of info.
if giles (or anyone else) knows all that, then they are worth the price.

Thats part of the service man! Give him a call. He will work all that out with you.

DVST8R, you bring up some very good points. If I had your mindset regarding these pumps, I probably wouldn't have dug into my fan when it broke, and found out the damn thing busted because of cheap grease and a 10 cent thermal fuse. I also may not have bothered dropping a diesel engine in a non-running gasser w/ no wrenching experience to speak because I could just pay for someone else to do it and it would be much quicker and cleaner. Instead of spending time doing my alignment, I could take it to a shop and they would be five times more accurate than I could be.
But will it drive just as well w/ me doing the alignment? Sure. If I'm at -20' versus the -15' Bentley has, that's not gonna be much. Hell, the darn things deflects a degree with an 500lbs in it anyway, so the alignment shop being right on at 15' and me at 20' probably won't make much of a difference in ride. However, by paying someone else to do it, not only do I loose out on my cash, but I also loose out on something more important imo, the experience I get doing it. And learning this stuff is way more valuable than paying someone else to do it.
$rant
It really bugs me when I see people discouraging others from doing stuff where they could learn a lot, just because that person doesn't think it's worth it for whatever reason. Be it to protect their buddy, because they have plenty of money, because they just don't like doing things themselves up to some point, or because of some other reason. I suppose this is just a pet peeve of mine so don't mind the rant. But, I said it before and I'll say it again, I don't like discouragement. Sure, maybe I can't put together the 100% pump that Giles can, but if I can do 75% of that pump for 10% of the money, and more importantly learn some stuff, I'll be in hogs heaven. :D
$endrant
-
exactly
id rather diy too,and get 75% for 10% cost any day
and learning "everything" at a good tech school doesnt hurt either
but even i know when im beat(pump calibration)
you totally need it(pump) to be set up on a test stand
i may be "backwoods" appearing on the surface,but look deeper,theres alot of "engineering" and time in my projects to brainstorm out any situation that may arise ,and its never "good enough"
put that extra 50% of time into it in order to get that last 5%more out of it
chances are itll be the 5%you need to beat the next guy
you could "assemble" your own hot rod pump,but you better send it out for calibration
and even then,you may need to know the guy because he may not wanna mess with an unknown frankenpump

well.... I can agree with this to a point....
wouuld you want some doctor who does brain surgery to get "80% of the operation"? regardless if your vehicle is 200 bucks or 2000 bucks. you don't want to blow up your engine because you got curious with a wrench and a screwdriver.
Pumps, like alignment; are things that should be left to pro's with the proper calibration equipment. I don't like having to pay for tires because of uneven wear, so I take it in for an alignment. I may get is CLOSE, but that only counts in horseshoes and hand grenades. Same goes with a pump rebuild.
Protect your investment and get it done by a professional.
I'm not screaming "giles" I'm just saying. if they've taken the years to train. they know best. But when reputation precedes that person... I let the reputation speak for them.
-
I encourage everyone to learn. But I know I like doing things right the 1st time. With a Giles pump I have no worries. I had to have mine rebuilt so I sent it to him so I can have peice of mind.

Didya read my second paragraph? ;)
As long as it's gud enuff, I don't mind. If I'm too brain dead to figure out it's not gud enuff then that's my problem. However, I've found that when trying to figure stuff out myself, I generally need to get into to the point where I'll know what's good enough, and what isn't. Like when I was referring to alignment in my second paragraph. :P
-
i'm all for the DIY stuff. pay a high price and know that you will get something working 100%, or DIY and don't know what to expect. there is also the fact that you will be plunging head first into what might be a pretty shallow waters... if you have time/money to burn and like to learn, then yea tinkering with pumps is all for you!
i may choose to tear into a pump someday and learn what makes it tick, but for now i'll just stick with what works. as mentioned, without calibration equipment, it will be near impossible to achieve what diesel shops achieve. it could mean the difference of 5 mpg!!! and pay for itself after a year or two.
good luck to those of you who choose to take the plunge!
-
You make some good points. I think why everyone is pump "shy" is that getting it 5% wrong can cause 100% of a very expensive problem. Believe me, I'm definitely in the Do-it-yourself class, but I have also realized that as a DIY'er, the motto you tend to follow is:
1st try....absolute destruction...but you learn a lot in the process.
2nd try.....marginal failure or success. It's a coin toss usually (luckily for me, it's generally in the success category)
3rd try....not bad. Close to stock in quality
4th try and above...now you can talk fairly knowledgeably about what you're doing. Even try a few things.
So, buy the Bosch manuals, read them like gospel, grab some pump tuning tools, and 4 pumps. Mangle the first two, get the third one marginally right and knock the 4th one right out of the park. Easy Peasy.
DIY isn't cheap for certain things......knowledge hurts the wallet more often than not. Don't mistake my comments above for cyniscism, that's just how I would approach acquiring this specific skill. I imagine given enough time, money, and motivation, we could all become good pump tuners. I'm putting this in my "prohibitively expensive" category.
Oh, writing custom ECU maps is also on my list of things to learn. I've started hiding all sharp objects from myself in preparation.......:D

Quality costs. You may get a pump to flow as much as Giles does, but his is the complete package. It runs right and It's set up for my specific engine and car.
Giles is "The Man" and everyone else is just a wannabe.
The name says it all;

I´m pretty sure there´s a IP-wizard in most countries that have a lot of diesel cars.
I´ve never heard of Giles pumps before I found this forum, instead I´ve heard of some pretty good pump-maestros in Sweden and Finland. It´s a big world and enough dieselheads out there to make some people want to learn everything about the pumps and make a living of it.
In my 12years of wrenching cars I´ve taken a car to a mechanic once! What I mean is: Try to fix things by yourself first, if it doesn´t work out, call the professionals!
An IP is not easy to tune, I guess it would take a LOT of testing to come anywhere near the performance of a professionally tuned pump, but it sure would feel nice if it did!
One would also need to have access to a testbench, and other magic stuff that a DIY:er probably doesn´t have at home..
-
All I can say is that the wonderful thing with VW engines is that it is possible for the shadetree mechanic to do their own tinkering. With that said, when it's time for me to get another pump, I will be hiring Giles to build it for me, I don't have the time or money to blow up my engine and don't want to kill my fuel mileage attempting to do it myself.
I guess it just boiles down to the fact that we all have a choice, and it's great that there is a resource like Giles out there.

Wow, this thread took off! I had no idea everything was so closely guarded! I can totally see where each and every person is coming from, both sides. I guess the shadytree DIY'er can still governor mod and play with the smoke screw a little, but from the sound of it the hard core perfectionists/racers should leave it up to Giles. I'm sure there is a different point in everyones engine building career when they will step up to it, and be able to justify it to themselves.
So . . . what exactly do you get? And what do you have to supply?
Timing pully, piston, etc. and is there a beautification option? some nice black powdercoat of anything?
-
You supply a pump and engine specs and you get back a fully rebuilt performance pump like this.

Then you paint it like this.

I guess I'm one of the malcontents that expects a layman's explaination from him as to what he is doing.
like i said earlier, i've adjusted my pump, my car goes like a scalded cat, and there is still room in the pump fueling wise. I kept notes on what I did, I went in small incriments, I verified changes through road testing. I think I can come pritty close to putting it back the way it was if I had to. I can, and have embarased alot of larger engine vehicles on the street. I have a stock 16valve, and the diesel will kick its butt.
What is detailed so far in this post is 1,000,000 times more than what Giles has put forth.
Yah, he is a technically oriented person, but I want some salesmanship that explaines what he is doing with out releasing proprietary information.
-
i don't think he owes that to you. if you don't want to buy one, don't. i know where i'll be going for my pump rebuild. i'd have done it already but i don't have the spare change....for the work and speeding tickets.
-
Cool, heck of a way to run a business though..
-
i believe the majority (or all) of his customers are happy. i wish more people would run their businesses on that principle.
-
i don't think he owes that to you. if you don't want to buy one, don't.
Great statement.
If you want to tinker, do it....just don't *** about those of us that want something professionally done. I don't care what he did, because the end result shows that he knows his business. :D
-
Have you asked him for a layman's term discription of what he does?

I think what is in question here is called a trade secret. It’s one thing to share knowledge about something you do as a hobby, and another to disclose information that could hurt your livelihood.
-
I feel it is just something simple that anyone one can do themselves IF they have a test bench and some "seat time". I wish he would tell us what he does also but if your making the money by not telling it'd be hard to let off the secrect.
I feel its has to do with timming alot. We can all crank the fuel up to where it smokes beyond belief. But knowing when to inject all that fuel is key. "life is all about timming" Look at the new electronic diesels. Low smoke but greater output on what i feel is cat piss fuel(USLD) :evil: .
I feel you have the right to buy a pump from him and go explore. But how many people are going to tear open their brand spankin new hot rod diesel injection pump?
-
When I emailed Giles, he wrote back. When I called him with questions about installation, he answered (on the first call) and helped me out. I have had a good experience dealing with Giles. As for price, my friend the engine builder once said "Fast? I can make it go fast - how much do you want to spend?" and that is what it comes down to a lot of the time. I just got my boost gauge in the mail, and I can't wait to install it & get that turbo up to 20psi so I can really let this Giles pump sing! :twisted:
-
Giles quoted me $950 to do a performance rebuild on my AAZ pump in my 93 Passat. I have a receipt for a std ip pump by someone local rebuild that was put into my other car a 93 jetta also with a AAZ. The receipt is for $1025 , so for less money they could have gotten a more professional job. If one wants to tear into their IP to see if they can figure out all the performance refinements that Giles does then have at it. I don't consider his prices out of line. Experience is expensive especially when working on something as picky as injection pumps. Cheers Dan
-
I see it like this:
A fresh pump costs $700, and anytime you can get 30-50% more power for $250, tats a deal.
If you go to youtube, and watch diesel drag videos,, there are a lot of wicked fast trucks out there. Most of em blow a huge soot cloud all the way down the track.
Most of the ones that are a few tenths faster make a puff of soot spooling up, then just a dark haze going down the track. Refined vs unrefined.
Its easy to make a VW faster, but the refined product will make it more faster with less loss of reliability and downtime.
-
I see it like this:

Voila!! the majority of the diesel shop have this price, the diesel tool equipment is very expensive, and it is the price to be paid, Example:I am an owner of general mechanics auto, and I gain my bread like that, what justifies that I charge 120$ to change front pad brakes on your car? if you change your brakes yourself on your car, that will take half an hour and will cost 30$.
In other hand, for a pump DIY'er, look and play inside a VE pump it is not a divine mystery and it's easy with some experiment, the hard section is to adjust the pump timing curve without bench test.
My estimated for a pump rebuilt:
60$ for a complete seal Kit.
2 hours @ ??$ to clean the pump and rebuilt it.
some $$ for extra parts, like better came plate or bigger head rotor (**one or the other, the result is the same**)
1 or 2 hour bench test @ ??$ (**is necessary to take into account that sometimes is necessary to open the pump to change or modify a parts**)
It's my point of view..!! :wink:
-
I can see both ends of the argument too. I mean, like Tintin said, you can change your brake pads yourself and save some cash. Likewise, if you have the knowledge, you could build your engine yourself or pay someone else to do it. Sure, there might be some tricks to engine building that you do not know but how much is that knowledge worth? Same goes for injection pumps. I don't know squat about VE pumps, so I'll let someone else do it, either Giles or Tintin. I've called around some diesel shops around here and their prices are pretty much in-line with what others on here are charging. I'd love to buy some pumps and play around with them but it's hard to even find a DI VE-pump core for less than $300. I just do not have that kind of money to "play" with right now and I'd rather put that toward a good pump that I can use and that I know will work.

I'm sorry if I came across like don't touch the pump you can't possibly modify it. Of course you can, by all means pull it apart, play with it. Yes there are some things that are difficult to get back together, but you will learn a lot, I know I have been down that road. When I first started coming around here (back in the old Host board days, and mailing list before that) we all had to modify our own pumps.
I have turned up a stock 1.6 IP pretty much as far as it can go, modified what ever I could, and turned it up again. (Fuel pins, star wheel, advance shims and springs, gov mod, pressure mods, anroid mods, ect...) and At the end of the day it was no where CLOSE to the pump that Giles built. I went from having a car with a 6puck clutch that would chirp the tires on dry in 2nd gear on a hard shift, to one that would break them loose and spin hard, just by mashing the throttle, it got better economy, it was more drivable off boost, it was a better pump. All for ~$1000 hell of a deal in my opinion. My last modified P7100 inline pump for my cummins cost nearly $6000...
-
I thought that each of the pumps was bench tested. They are not. Giles even wrote as such. That was quite a shock to me, as I've bench tested many pumps for myself and for customers.
Within this thread, each post exists a division of sides, and largely those who own a shop, seem to side with *secrets*, and those that do not are more for *open source* idea sharing. This is quite normal. Of course, there are variations, but opinions should be taken with a grain of salt.
If you know how, tuning these pumps is no magic, and unlike building maps for gasoline cars which can be very power unit and system specific, most of us already know, diesels are far more forgiving.
As far as timing curves are concerned, again, there is no magic, only knowledge gained through experience.
-
Theres only one way to settle this.
I propose a duel.
not with pistols but with injection pumps
Giles vs the haters.
-
That sounds fun. But we have to determine what the competition is based on. Peak power, area under the curve, BSFC, emissions, cost, etc...
-
I don't think any one is a "hater" by any means.
The reason I don't have a giles pump is the same reason i don't have 3" DP or a PP intake mani. I'm driving a VW diesel because i'm cheap, poor, and crazy. And i love diesels. But i have this sickness where i must modify any and everything possible. It started with lawnmowers an go-peds then cars trucks and dirt bikes.
It's hard to put alot of money ($1000 is alot to me no matter what it buys me) in to an 1984 VW rabbit.
Now this is not saying i'll never own a giles pump. It's just not right now.
How many of you would still buy a giles pump if he told you that all he does is remove one bolt and replace it with a shorter one and take a shim out of the timming piston?
I'm sure most of you still would because you would get a product back that is known to be what it is said to be. Even if he told us, we will never have his experience.
I imagine after the 100th pump he no longer needs to set them up on a test bench. He remebers every motion with his eyes closed.
-
Head on head friendly competition is always cool. I am not talking about my buisness is better than yours, or I beat you and it was cheaper(and blew up later!). SO ...
head to head on test machines? On cars at the drags? On a base engine on a dyno? People still don't have to give up the ancient chinese secret :D
Of course some one who wants to go up against G. should probably contact him and let them know about this thread. :wink:
-
I can see it now, Giles is going to ban me from purchase in the future because I started this thread! Although a little competition would be pretty fun to see. If only I had a dyno and a weekend of free time . . . any takers
On a side note does Giles like media blast the pumps or something, they seem to come out looking fresh! Could it just be a simple chemical bath?
-

Giles does a full rebuild, replaces all the seals and other wearable parts which is the bulk of the charge, and is dead on price with what other Bosch shops charge. You're asking a non-comparable questions.
If you asked would someone would pay $250 to have him make two or three tiny adjustments inside a finicky hydraulic computer like a VE pump where a few bits of dirt or one misaligned part could ruin it, put it back together and guarantee it'll work well, then yes, I think more than a few people would happily pay him $250 to do it.
I did, and I've worked on turbine engine fueling systems similar to the VE setup. It's not magic, it's having the right tools, hand skills, and experience.
I'd play more myself, but I don't have the time or money to do it. I had a pump with leaking seals from the ULSD change, I need it done right the first time ASAP, and he certainly did a great job.
-
Thats what i was asking. I guess i worded it wrong.
Many guys on here send their pumps to giles just for a factory rebuild no mods even if they live several miles away.

His plain vanilla rebuild prices were cheaper than some of the local shops here in BC. Not a lot, but it covered the shipping charges.
There were a few guys that quoted me cheaper, but on questioning they were just putting in a seal kit, not overhauling the pump. Buyer beware.

I've kinda skimmed through this post quickly.
Giles' latest pump put out 160cc's with a 9mm plunger.
Each and every pump is bench tested before leaving his shop. If someone thought they had read something contrary to this fact, there must have some sort of misunderstanding.
Giles is very busy.
The best way to contact him is by phone.
As before, but even moreso in his new self-owned shop, the pump mod package is definitely proprietary information. It's simple people, this is how he feeds his family. Get over it! If you think you can do it yourself, do it. Nobody is stopping you. It's not as easy as it looks. I have personally seen several pumps, this year alone, that have ended up in his shop to 'undo' the mess that their owners had created. 4/6 of them from this website.
His price is very competative, the best value in the industry in my opinion.
Bottom line, it's your choice. Crap or get off the pot, but don't complain about it on here!

I went to an auto/diesel mechanic school in the '70's where we were given a very brief intro to IPs. This was a time when all diesels had mechanical IP's. It was very hard to get an apprenticeship in an injection shop and for those who did ,it took years before they where entrusted to calibrate IP's and they worked for less $ than other apprentices.The journeymen pump men have always guarded their secrets because it took them years to gain the knowledge, just like a good carb man. We live in a capitalistic society and everone basically prices his or her talents in the marketplace and we are paid accordingly. I have worked on many large and small diesel engines over the years and I would never work on an IP without the proper bench and knowledge. Also IP repair prices really haven't gone up that much but has anyone priced a test bench, shop rent, insurance etc.
Price hotrod mods on the Cummins IP's!

It have there people who are able to make a good pumps without needing a test bench, here in quebec, I know some pump shop with a very good reputation which are unable to built a TDI with a mechanical pump, even with the assistance of a test bench :wink:

Where's the one that shows the untethered 14cm bounce?

LMAO!!!!

I've rebuilt and tuned many bosch VE pumps now, I can build a pump fast enough for most people, but if I ever built a big badass motor again, I'd likely be sending my pump to giles. His stuff is great and you can't beat the prices for what you are getting.

Or at least part of the answer. Saurkraut pointed out that the videos I've just posted are a good answer to the question this thread was initiated for. There will definitely be more info to follow, but if you're still curious about what we're doing here that you (or even we) generally couldn't do at home, have a look at this thread (http://vwdiesel.net/phpBB/viewtopic.php?t=11629).

In the the boost fuel video I noticed the graduated measuring dealies weren't exactly level. Is that a difference in fueling from the pump, or just the way they're set up? Oh, and now I wanna make my own test bench too. Thanks a lot man, all I need is some other unpossible project. :x :P
Anyway, how does the machine record timing events, piezos in the injector dealies? Looks awesome man. :D

The slight disparity in fuel levels within the graduated cylinders in the full-boost fuel video was because we did this video unscripted - you were looking at a preliminary test before Giles had even finished calibrating the pump, so the levels were not yet perfectly even. It was a matter of fuel delivery from the pump; The disparity is well within manufacturer specifications, but ideally (especially in a performance pump) when we're finished, everything is perfectly even.
As far as the timing measurement, that was on the other side of the pump, which we just didn't move to show in the video. It is a mechanical, piston-type timing gauge measured in millimetres to show internal pump movement within the housing.
Glad you like it. :)
