Just checking, need to install a gas line for a 28 speedster. Any pros or cons of copper versus steel brake line tubing?
Thanks

I would use steel brake line material. Copper will work harden from vibration and crack.

Steel is best. Copper can become brittle and break. There is a product that is a copperized steel with zinc outer coating. It withstands up to 3000 psi and is fairly easy to bend or flare. Check with your local automotive supplier or JEGS on line.

Have had copper for 43 years no drama.

Some say "Street is neat". I prefer "1928 is great" I have documented my 45 years with a 1928 Chev Tourer, from 1973 to 2018, and regulary add other items that I hope are of interest to others. Your comments are most welcome.The story of the Red Chev can be viewed at http://my28chev.blogspot.com/

 When I bought my '33 coupe as a basket case in 1979 it had a copper fuel line, no problems so far! ??

In my humble opinion there is a difference between using copper on fuel lines where there is very little pressure vs copper on brake lines where there is much greater pressure when braking.

I have had copper fuel line in my '25 for 40 years with no problems, despite the fact it can work harden. This usually causes problems only in the line that runs from the vacuum tank to carburettor. A full circular loop usually fixes this by allowing the tube to flex without work hardening and is a common sight.
Steel is always a problem with rust forming over time, and I am sure car makers use it only because it is cheap.

I have seen copper plated steel tubing.

Done, it was nice not having to straighten out the copper line to make it straight, but a little more difficult to bend.
Looks great. The brake line that I used had an industrial green/gray finish to the surface.
