I got this advice from a guy called Jim at the Passion forum at
www.mtbr.com (he might also be around here)regarding this image:
http://superelectric.net/transporter/0004.html This is his advice:

"Looks like the mech fuel pump is leaking at the base. I'd go ahead and
replace the pump (super cheap) along with the seal, if it was mine.
Check and see if it's a oily/gas mixture, if so, the diaphragm is
leaking. I've ruined a perfectly good 1600cc in a beetle with a leaky
diaphragm."

I guess changing the pump is a fairly easy (is it really needed,
should'nt it be enough to change the gasket?), but I have no idea on how
to change the diaphragm. Any online descriptions on the procedure? And
how expensive is a new fuel-pump?
