Jeff, your subject line has to be the wurst pun of the evening!

My auto parts store here fabricates steel brake lines and also stocks
straight steel brake lines with 3/8"-24 UNF flare fittings on both ends
in various lengths. I wanted him to make one for the 164 to replace one
that had gotten squashed against the axle housing by the tailpipe, but he
went on vacation before he got to it. So I bought the straight one and a tube
bender (although I did most of the bending with bare hands) and the only thing
was that it had male fittings both ends, where mine needed a female fitting on
the inboard end. After bending the tube, it was about an inch and a half too
long on that end anyway so I took it back to them with the right fitting
from the old line and cut to the right length and they put the double flare
on it for no charge. The lines are cad-plated or galvanized and quite reasonable
in price. I'd say that stainless is not really a good choice for these and the
standard plated steel lines are great. Stainless tends to work-harden and the
beginning of the flares is a place where they are both work-hardened and also
under residual stress. Add chlorides and you have all you need for stress corrosion
cracking. It doesn't happen very often but at least you can see the rust on
plain steel.

So in your position I think I would go looking for an old-time parts store that
does hose and tube fabrication and take your old lines to them.
