>  If that's not it, try a genuine VW pump.

Incidentally, the '86-91 pumps I am currently shipping (for $49.95) are
genuine VW, still in the original VW boxes.  (Can't always get them, but I
have about 20 left at the moment.)  My '83-85 pumps are German made Hepu
brand.  These are two of only three brands I know of that are still German
made (the third being Laso, which I haven't seen in a while).  Most of the
other brands are now Italian (not that I've personally had any problems with
the Italian ones).
