[s-cars] Fuel leak 93 S4

If you are going to have this line made up yourself, run a hardline from the
flex hose at the fuel rail along the firewall behind the POS/connector rack
to the flex hose at the fuel filter. Fit a new section of high pressure flex
hose at the filter and have it high pressure swaged to the hardline.
Personally I'd try to get the replacement line from Audi; they probably have
a bunch made up for the North American recall. You can also buy a line for
an A6 (I think the P/N is 4A1 201 529L for the NA models; it might be
different for LHD models). It will fit with the exception of the connector
to the fuel rail; you'll have to modify that to fit your S4.

Thanks for the advice everyone.
It would seem getting a hose made up to go the whole way from filter
to firewall (or manifold?) would be ideal.
Or is that faulty logic?
