Dave,
I see what it says...thats crazy.  Unless it was maybe off an industrial/marine engine...but that'd be pushing it. All the lit I've seen on the TDI industrial and marine engines and I could swear that they were still electronic control...and def. never a 12mm head/plunger setup.
 There are variations of DI pumps out though that are "hard to find" that have the correct nose length, direction of rotation and even share the VW style gov. setup (a stock 4bt pump's gov. can also be setup to run VERY nicely in a weighted vanagon...not so much fun in a car) from other cars that are on the road.
On that note too....there are a few guys overseas selling the "mpumps" claiming they are OE for vanagon applications...
Makes me wonder what it is from as it def. isn't a 4bt pump base...

I'd be super suprised if it was a VW pump though...

I have always been against "mechanical" TDI injector pumps, but I installed one in this car as it was an "out of the box" Bosch solution that wasn't a hybrid bastard of parts from different pumps. The pump is a factory VW pump from a 2000 somethingorother that is sold in the Farfrumhome market, so if you are ever in Farfrumhome you would be able to get one of these pumps, but for now I am going to hold the cards close and get some of these imported for sale in the fall... maybe!


I saw that too, seems like it couldn't be that hard to find with the clues he gave and a few international e-mails.

It's probably a Volkswagen LT  2.8TDI (4cyl, 125HP) equipped with VE  "mechanical" 12mm pump,  it's the same engine as in Renault master and iveco daily, these pump have 12mm head rotor , but the rev limiter is not to 4500rpm, it is to 3800rpm,  there is not VE12mm pump with a rev limiter higher than 3800rpm, but it's easy to rev over these limit with eagerness  :lol: .

I ever succeeded in finding one of these pumps, they are very difficult to find one.

lol...

Did VW make the farfrumhome? Sounds like something out of OZ :)

Anyways... its cool if its the real deal...but ask around about the concensus on things "mechanical" and "TDI" and you'll find that a good number of those that have had their pumps "built right" and have built them their selves are happy with their setups...

and also... if you start with a DI pump there is less "hybrid bastard parts" from other pumps thrown into the mix. Also, there have been tweaks that mechanical guru's have found with the mTDI setups of pumps, etc. that make things a whole lot more fun and better suited for the TDI engine. Not to sure as if I like that reference, but you have to no the character your working with as well (and I've spoken to FastForward before, he was interested in the 4bt pump back when I first started working on mine...).

The Country TDI is def. cool though :)

Send out the hounds and find a few of the pumps across the pond!!! That'd be cool...

Hmm...I wonder...

  I'll have to post up in that thread and ask him what the redline is :-)

EDIT- done.

The "mechanical" pump has a red line of 4400 or 4500 - which I think is what the factory "electronic" TDI pump does.


  The plot thickens, sounds like a sweet pump though...

VW LT, cuick google find that it's a eurovan.

obviously can't call it a eurovan in europe, haha

2.8TDI, 158ps,

it's a common-rail, though, atleast in the mk2

I see nothing about the LT using a VE pump, unless I missunderstand how common-rail works?  (single, common pressurized fuel rail with peizo injectors for each cylinder?)

oh, found it,

2.5L, not 2.8L, and 5-cyl

Can't be a 5cyl, because this VE pump has is a 4 cyl model. I am familiar with the 2.5 van engines, rebuilt one not too long ago.

A 2.8 4cyl tdi sounds great, especially if it would fit in an early watercooled chassis.

The pump is interesting.

I am more interested in the bolt on parts used to swap an 020 to an 02A.

What can you European guys tell us about them? Part numbers maybe??

2.8TDI=158HP for the common-rail version, year 2003, code engine AUH, BCQ,  but the older version 1996....  have 125HP code engine AGK.

Call a bosch shop and ask for the 0 460 424 138  :wink:
