Yes, the two systems (75 to 93) are very much different but parts share
many functions. While the EV has a fuel rail that is much more reliable
then the lines and hoses on the bus they both have nearly the same fuel
pressure.
My point was that the metal ferulles used on the bus had given many
owners questions much the same as the metal crimp fittings on the EV.
Do you think the spring type clamps used in a few places on the EV
system are better then the high quality German (not just plane hose
clamps) hose clamps I have used on many other VW's?
It seems like the spring action of the spring clamps would maintain
pressure when used on a new hose. However, I replaced a coolant hose on
this EV some time ago and the factory spring clamps took quite a while
to seal the joint completly. Not too much a problem for coolant but
another matter for fuel!
