I finally go my 1985 Audi 4OOOs Fuel Injectors out, successfully!
Constructed my own L-shaped bracket.
Inserted a long punch into the top part of the bracked
and used a heavy weight rubber mallet to "jerk" the
injectors out. Brute force was requiered.
This not a recommandation, unless you know what you are doing!
Everything has to be angled correctly and properly supported.
The injectors checked out ok. Good dispersion and no drip.
Now, here is the question:
Has anybody ever replaced the O-Ring and the Seal-Ring
on the injectors?
I am afraid to slip the heavy seal-ring over the injector
into the designated groove. It might break, I think.
