[s-cars] Fuel Odour from Under Car

[Fred Munro]

Sean;

I replaced my lines with generic galvanized steel tubing of appropriate
diameter. Only Mark would be brazen enough to use copper. If you have an ISO
flaring tool you can use the male fittings on the old lines to connect to
the hardlines coming down from the engine bay. If not, you can cut the old
lines close to the front couplers and use compression couplers to connect
the new line to the stubs of the old lines.

HTH

Thanks Fred, Mark and all:

So assuming that the metal line is rusted, is it possible to cut out the
bad section and graft in a new one or do I have to buy a whole new
length of line?
