Hello,
Where can one source a 10mm or 11mm ve pump head from? I don't think I'd have any luck finding a peugeot pump, nor do I want to buy a new bosch one.

I'm pretty sure Prothe has them pretty cheap, how good they are is anybody's guess, maby someone else out there has tried one.

Did TDI's have a 10mm head?
What does it take to make a TDI head work in a 1.6 pump?

TDIs from a 5 speed have a 10mm, automatic is 11mm

Why do the automatics require larger heads?

You could contact da-brt(check PB for e-mail), he has 12mm heads in stock.
And also he makes complete pumps with 12mm heads ( new or rebuild ones )

I was under the impression TDI pump head=no go on a IDI injection pump?
?
I found a 11mm pump head...it was $900 for JUST the head!!!
ended up with a IDI 11mm china pup head for $75..we will see f it lasts.....?

Have you installed it yet or tried it, I too am curious about some of these Chinese parts like this. I've heard both ways but no experience at all myself and a lot of times it's not the part's fault but the way it was used or missused. I know if I was gonna do some pump experimenting and the part one place was 900 and 75 somewhere else which way I would go, Hop Sing here I come
For that kind of money it's worth it just out of curiosity compared to $900. Maby the stuff works but just doesn't last as long and maby it does but if it don't, just buy another one. It's not as likely to hurt the engine if it fails like a piston or something like that assuming you have an EGT guage.

A broken plunger probably wouldn't hurt the engine, but might trash the insides of the pump or delivery valves/injectors.
Have you ever used any of these Chinese fuel related parts yourself personaly? I figured someone who works with this type of thing as much as you do could maby shed some light as to weather some of these parts are worth giving a chance or how long some of it lasts?
Again this is only just the pump and injector type parts.

Very interesting info, all.
That story is kinda steering me away from the chinese made pump head route.
So, what exactly does it take to put a tdi head onto a 1.6 pump? 1.9 camplate?

Why do the automatics require larger heads?
They also have smaller injectors. It changes the torque curve I think
In regards to Chinese heads, we've used a couple at the shop. The last one being a 14mm in a cummins VE pump. You can clearly see that the Chinese heads are made of an inferior quality metal. It's a lot softer, and the machining is no where near as precise as Bosch. I can't comment on longevity from experience, but I speculate that they will wear out a lot faster. If you do plan on using Chinese parts, I'd recommend at least a 2 micron fuel filter, and ALWAYS using a high quality fuel lubricant like Stanadyne. Although, everyone should be using a lubricant anyways....
I'd get a used Bosch head over a Chinese head any day, even if it was 3 times as expensive.

I always did have a feeling that the metal was a cheaper grade to start with would affect how long the part lasts just by itself before anything else is degraded but I never tried any of the stuff. In regards to the filter how many microns is the stock filter and would a 2 micron have the same affect on the engine as a restricted stock filter?

so basically nobody can back up the china injection pumps heads as being short lived with any real data?....
My cummins filter should keep my pump nice and clean...and I have a lift pump so no worries on VE's fuel supply.
I would rather spend $75 and see how long it last vs..$900....if I ran the china and it is short lived then maybe I would change...but I can replace a lot of $75 pumps heads for $900...and diesel VW parts are not that easy to find in the us...even in the GTD classified it's hard to find used pump heads that are 11mm+
TDI pump heads don't work with IDI pumps...RIGHT?!?!!?

A proper 2 micron fuel filter will not restrict the flow any more then a stock filter. I forget what the stock filter is, around 10 microns maybe? Don't quote me though, I'm just going off a foggy memory.
www.ebay.de usually has a nice selection of pumps. How much boost are you running that you need a larger head?
