Hey I wanted to know if anyone has a diagram or pictures of a adapter to use the cummins fuel filter on a 1.9TD. I have access to a machine shop, just need a little direction with this.
-
you could always use the CAT 1 micron filter.. all you need to make is a bracket to hold it in place (home depot will have everything you need)
-
I believe most truck filters have the same size fitting so if you go to a truck supply shop, get a racor/parker filter stand and you'll be able to just screw it on. Otherwise an adapter will have to be machined. I looked for a while for pre made adapters with zero luck.
-
The reason I want to use the cummins filter is that it is made to be the only filter in the system. Where as the cat filter is made to have a water seperator inline with it. This is research that was done and written about by QuickTD, I was at his place getting a crank machined a while back and I remember looking at his set-up, but I never inquired about it until I did my searching. I have access to a full machine shop and I have the skills to machine/design a bracket for it. I will be getting a stock bracket off a N14 cummins motor, I will just have to figure something out for the pre-heater......any ideas?
-
I would think he easiest and cheapest way to have a preheater is buy either a 12V or 120V filter blanket. Actually i think the 12v would be a wrap around and the 120V could be a small stick-on block heater. I've used both, with equal results but prefer the 120v so there's no killing the battery.
-
The only other thing I thought of was that the stock VW filter has a fitting for the return...where if I remember correctly the cummins one only has in and out. I would have to drill into the bracket so that the fuel can return. I would like some input from someone that has done this so that Im not messing around with this for ages. Once I have the parts in my hand I will see what I can do.

This place has all the heating stuff you should probably ever want.

thats a pretty cool site. the inline heaters seem quite reasonably priced :) are those thermostatically controlled though???

if you get a 04.5+ cummins you will only need banjo fitting to adapt.
here is my 04 set-up...I had to fab a little adapter to make the old style work...if you gonna do it find a newer filter housing(04.5+)

Thanks for the pics.
I plan on using a screw on type filter from a N14 cummins along with the bracket...I looked up the bracket in a parts catalog I have and it has npt fittings on it, I think. Im gonna get a bracket from a junk yard. I will just have to mess around with:
1) mounting the bracket to the car.....not a big deal
2) going from threaderd fittings to the stock fuel lines in the car....not really a big deal either.
I will be collecting parts soon and I will take pics.

nice please do post some pics when your done!!
just a FYI for anybody else reading this or researching fuel set-ups...the Dodge cummins fuel filter has a 5 micron filter option too.(baldwinn makes a 5 micron vs the stock fleetguard being a 7 micron.)
-
Anyone know if I would need a lift pump for this setup??? due to the increased filtration I would think that the IP would have a harder time pulling fuel throught the filter???

as long as your system isn't restricted in any way up until the filter, it should be okay. 1 micron filters will probably require a lift pump though... if you want to go ahead and install a lift pump anyway, it wouldn't be a bad idea. just $$$.
-
any recommendations on lift pumps??? is there one I would be able to grab at the junk yard? I dont realy want to invest too much money into a $200 car. hahahaa Any diesels come with one stock?? I have never looked into lift pumps.
I just found this using google....would something like this work???

That's basically what I'm using on my conversion project
http://vwdiesel.net/phpBB/viewtopic.php?t=15633&postdays=0&postorder=asc&start=15
I have an aux switch to power this lift pump... you should not need it unless: You ran out of fuel and need to prime the system, Changed your filter and need a prime, you have a _small_ leak between the IP and the fuel pick-up, its really cold and you have some contaminate partially blocking your filter....

If you have a PnP around ya, the mk2 gassers had a in-tank pump that works great. It's low pressure like around 4-5 psi and gets up good.
They use the low pressure pump to feed the high pressure pump mounted where our water separators are.
53willys just finished a gasser conversion and left his in-tank pump in place.
We discovered when we did the first start up that you cant suck fuel though that pump, not even a little. It has to be running to get fuel through it.
-
I was also looking into the golf 3 with a ACC engine (1.8 8v fuel injected carb) the pump is rated at 1.2BAR = 17 psi. Thats a little too much but I was thinking of running a pressure regulator to set it at 5lbs. But if you say that the mkII pumps run at 4-5lbs I should be able to get one. Is there a way I can test it to see what pressure it runs at before I install it in the car???
-
Try looking up " Facet " fuel pumps on Ebay. They work very well. I think you can also buy them at NAPA.

I wished I could have done that with my Caravan diesel conversion, but mine was a high pressure for the fuel injection.
Here's a pump for $32:

If you first search for "diesel pump" they will offer you a $10 discount, so with shipping you'r looking at something like $26 in your hands. Its the pump I have on my Dodge Caravan conversion.
