[s-cars] Fuel Odour from Under Car

[chris chambers]

Sean,

I had this same problem with my Audi 5000 some years ago.

My fix was:
1 Purchased standard Steel lines from the local NAPA dealer.
2 Removed the rusted lines from car, cutting the line and saving the
metric fittings.
3 Bent the new line to replace the old ones, in my case I had to use
two lines coupled together to replace the old one.
4 Cut the replacement line to length, installed the metric fittings on
the new line and flared it with a flare tool.
5 Installed the line
