If I had an 11mm pump on a 1z/AHU I would drop down to 50k belt changes or switch to the wider belt setup.
I just want to note that the AHH belt is not wider, it has a different part number, same goes for the tensioner, but I cannot physically see a difference between the two.

back from the dead... again :) i'm planning an 11mm pump on an ahu build. related question, can an 11mm alh pump head be installed on an ahu pump? or is there more to it than that? i could get a 11mm pump head for a good price, and have a good ahu ip core....

I have a really weird question I have a 1998 jetta ahu and rebuild the injection pump and the bottom of the quantity adj the part that slides into the sleve has like a ball end on it, has broke clean off I have a pump from a 2001 jetta ahl and I was wondering if i could just switch the quantity adjuster or be cheaper to machine the ahl pump to work

Holy smoke, all you guys shimming the pump over are doing it the hard way. You just have to adjust the belt tracking by rotating the pump bracket. Sprocket down, lines up makes the belt track closer to the block.

Andrew Libby is right....no shim BS needed...My ALH Pump swap is washer/shim free...

Why not just use the alh pump and bracket instead of going threw the trouble of machining the old ahu bracket not sure if there the same or not but if someone knows it be great because I can get a 11mm alh pump off an automatic and the bracket if it bolts right up that would be great

It's not possible to use the ALH one it's completely different!

If you need an AHU bracket professionally machined PM me and I can have it arranged for you!

Swapped an ALH 11mm onto the red death today. Figuring out how to de-pin/re-pin the harnesses was basically the hardest part of the swap. everything else just falls into place if you have the bracket machined properly.

i made a terminal tool from a harbor fright tweezer set but i only needed the smallest one of the set. i just looked at this guys video ( https://www.youtube.com/watch?v=bbW9Yc36RPE ) and figured i could find something that would work at harbor freight or walmart. notice the tips of the tweezers bent inward (1st pic) which press the tabs inward (3rd pic). Pin swap list also shown in 1st pic, stolen from PAGE 1 of this sticky.

Just used this thread to repin an injection pump connector but i'm putting an entire ALH into a B4V so i repinned the B4V wires into an MKIV headlight connector (same as mk4 harness side pump connector) ... great guide! thank you :)
