Nope, not me.  I can't for the life of me remember who it was that
had to recently replace the short line that goes from the regulator
to the fuel rail, because it was leaking around a fitting.  Maybe it
was Peter S or Paul Levano?

What I did learn was that new washers must -always- be used whenever
you take a banjo fitting off; it'll never seal the same again if you
don't.  They're available at any VW or Audi dealer, they've got 'em
by the dozens and they're maybe 20 cents apiece or something.  I
think I posted the part number a while back.

This is a pretty easy check...if you pull the control line off, fuel
will come out.  I think the V8 owners were having problems with
fuel-caused hydrolocking(!) or it was at least a serious concern.

Another way to check is to do the output operates the
carbon canister valve.
