You are correct Larry, the 1985 was CIS-E - Digifant II didn't start in the
GTIs until 1988.  Occasionally some people have had problems with their
stock Vanagon pump - I would say 1 in 6 or so.  As long as it is working -
that is the main thing!

David,
I don't think the '85 Golf had digifant II, did it? I believe it was the
CIS-E, requiring the pressures you indicate for that engine, not the
much lower Digifant.
All I know for sure is that in my conversion, it would barely run, and I
tried three Vanagon pumps with no improvement. Popped in the Golf pump
and it ran fine.
And yes, the '80 Audi pump would have enough pressure, too.
