Well, as usual, if I want to know something or find something, I ask my HAMB brothers and sisters. My 3x2 set up has some pretty cool looking aluminized steel fuel lines on it. I want to re-do all the fuel lines and would like to use the same material. Anybody know of a source for 5/16 or 3/8 aluminized tubing? I've done a Google search but can't seem to find any. All I can find is aluminum, which I want to stay away from. Too many connections on my setup to risk the work hardening and cracking issue.
