Jim i right, on late FI Bus, metal line were used

I still wonder why they stoped doing so on a very important issue, fuel line!
Of course, they (VW) didn't think theirs products would last for 20+ year.

So that said, i have to say that the original FI line were extremely good
(same for the multiple flex coolant line). On the other ahnd, the wasser
engine (a poor modification of previous Air-Cool engine) were also, i think,
a money issue.

A have a few van in the shop now, those day i drive a Carat 2.2L Subi, why,
it's -17C (1F), and it's the only one starting up fine, like any other
modern car, the wasser and it's injection system is.... pfffffff... i won't
say what i really think of the VW FI.

This van is so pleasant to drive with 130+hp.

And to all who wonder about size (5/16, 7.5, 7...), just put some new one,
period... anything will be better than those old one, the clamp is the one
you should wonder about it's quality. The cheap one will "stripped" if to
tight, and please, don't use water hose clamp!

Regards, and have a great new year!

It's called MONEY.  To save on production costs,VAG goes with the least
expensive (read: cheapest) method of performing the same thing with plastic
and neoprene instead of metal lines, compression fittings, etc., that the
more expensive manufacturers (ie: Saab, Volvo, Mercedes, etc.,) choose to go
with. Up until the mid 70s, VW did use metal lines (with short hose ends) on
some vacuum lines on the Beetle.  And some people wonder why VW's quality
control went down the tubes after the mid 70s.  Again it's called MONEY (or
in their view "cost cutting" which more often than not translates into
"quality cutting" in my opinion).
