So I have and AAZ head and AAZ injectors on my 1.6 TD block.
The AAZ injectros have a noticeably longer body than 1.6 injectors, so the stock
injection pipes don't fit very well.
What injection pipes have you used with 1.9 injectors and a 1.6 block?
At least T2 1.6 TD and T4 1.9 TD pipe sets are available for me.
I don't think AAZ pipes will work either as the pump sits at a different angle on the block.
-
I would think u must use 1.9 lines, and that is what I've read on here in the past
-
Would T4 1.9 TD lines work?
Golf III / Passat ones aren't available at my supplier.
-
I wouldn't know haha, I do have 2 sets of aaz lines tho, I'd send them to you for the cost of shipping but I'm not sure if they are the dual stage lines or not
-
There aren't any lines that will fit that combination without bending them because the taller injectors were never used with the shorter block. If you use 1.6 injectors you could use 1.6 lines. 1.9 lines won't fit because the 1.9 block is taller.
-
Well, which lines would require the least amount of bending?
-
Probably ones from a Mercedes 300 series 3.0 L 5-cylinder.
-
Isn't the 1.9 pump body also a bit longer than the 1.6?

The 1.9 has an extended nose, but that doesn't come into play because it is on the other end of the injection pump bracket.
-
I'm using the 1.6 TD lines on 1.9 injectors with the long delivery valves.
Only slight bending was needed to make them work and can still be used on 1.6 injectors.

I have an Iveco 2.5 TD pump which is a LOT longer than a 1.6 pump :)
I guess I'll have to do some bending no matter what, I just hope that won't affect flow rates of the individual pipes...
Of course I could get a set of second hand pipes first and then use them as a template. Every part on this engine needs
to be new you know ;)

Have you tried them? This is an interesting idea. I wonder if the pipes have the same diameter.
Even very small diameter differences can cause surprising effects...

the PUMP is in the same spot as the 1.6, is it not?

Mercedes uses inline pumps, it would be a miracle if those lines would work on a VW 1.6/1.9 setup.

i dont see 300D lines working easily...
the merc uses an inline Bosch A pump..
-
PTL It's a MIRACLE! The Merz lines work fine. Same thread/fitting at both delivery valve and injector. Same length. Same diameter. BTDT. I recommended them because they are cheap, readily available and less bent up than most other lines.
-
Is it safe to assume that you are re-bending the MB hard lines to work with the VW pump?
-
Yes. I only said those because there isn't a set of stock lines that fits.
-
I thought you were just being a butt hole, I wonder if it is a common flare that we could just totally make our own
-
im not 100% sure but i think you can get bendable lines..like they used to have lines we could bend in the fuel lab at my old engine shop...maybe try someone like schied?
they are probably" test" lines for fuel labs or somethin...or else ya gotta go custom...ive seen dodge boys with custom lines so where do they get em?
make them equal length tho i know that much...its not the greatest to bend stockers,but hey sometimes ya gotta do it. ..from what i understand when ya bend em,plating can flake off inside the line and plug your injectors...but ive got bent lines on sootyvag for forever..a little bending is ok probably,but doin loop the loop isnt cool

This is one of those rare times when I wasn't. :P

I've cut up quite a few stock lines and have never come across anything resembling plating inside the lines.
