I am looking at replacing my entire fuel system (tank to pump) on my 85 Cutlass. I am having a hard time finding direct replacement fuel lines for my car. Are their any companies that make them? I have found brake lines, but not fuel lines. If anyone has done this please let me know. Thanks. Also, I did an engine swap with a 72' Buick 350 and it doesn't use the return line to the tank. I just have a breather on the line now, when I replace the lines can I switch to a two line system?
