Raimund, do you want to fabricate these hoses yourself or are you looking
for someone to make them up and send them to you? I can make custom AC
hoses and I have most of the stock Vanagon hoses sitting here on the shelf
to use as guides to make the new ones. Let me know if you would like me to
price out making up new hoses for you and shipping them to Germany. They
would all be brand new barrier style hoses suitable for R134a of course.
As for your leak, I would suspect the expansion valve as they have an end
piece that is epoxied in place (steel piece in an aluminum block) and over
time the epoxy can start to fail causing a leak in a place that is hard to
see unless you drop the rear unit.
Ken
PS Very soon we should have quality reproduction rear AC Evaporators
available for the passenger Vanagon (I can also have new Westy Evaporators
made up if there is interest).
