I was able to see the ECU number through the air intake grill in the left
rear fender .
The Bosch # is 0 280 000 048 VW # is 311 906 021E.
Also on Samba I'm being told that the injector seals of the kind that are
sold by most on-line and FLAPS only last 2 years before drying out and
cracking providing a leak . Mainly by one fellow who says you should use
green CIS viton O'ring type . Last ones I got from bus depot and they looked
just like the one VW sold like they were molded black rubber , by molded
they have a small ridge around the center.
I replaced mine in 2009 and just looked and see no cracks . He claims it's
the fit around the injector tip that is the issue . What I see once
compressed they seal around the tip/ yellow plastic cover and the base of
the injector . I cannot rotate mine or move any injector one bit. . He also
said seals that sit unused are shot
I was also told you can't use or find thin enough gasket paper to replace
the gasket on both sides of each runner to intake plastic spacer.
I also wanted to ask if you have 4 of the runner to IAD hoses and maybe the
injector tip seals ? and if so what would they cost. I can find then
on-line yet the shipping is a killer.
