Lots of Rat Rods running Copper fuel lines for that old school look. 914 fuel lines are never seen. My Question is WHY ? Tangerine racing has pre-bent SS lines for a very reasonable price. Save your self the hassle buy SS lines. |

That is the only reason, i have not heard of anyone doing it with copper before. He is a 40 year Porsche mechanic and i trust his abilities. Thanks for the response |

I would be nervous about kinking soft copper while fishing it through the tunnel. Especially if it was just enough to starve you at high rpms.

that's what I do! Group: Members Posts: 20,065 Joined: 27-December 02 From: Port Hope, Ontario Member No.: 26 Region Association: Canada |
I wouldn't, the biggest fear I would have is if the copper line is just sitting in the tunnel, it's likely sitting in rust dust. Steel and copper doesn't get along together. If was totally suspended with copper or plastic covered hanger/clamps with proper grommets it might be OK... But why would you do that?
Original or SS lines is all I'd trust . SS kits often have a return line, but you only need one line for carb, so if you don't see one just ask for a single line. |

Copper is soft. Stainless is way stronger. Just use what is proven. Not like price is an issue. Especially when you can buy pre-bent lines in a kit ready to install from a known reputable vendor.

I used truck metal brake line for the front area,easy to bend with the correct tool which I had,strong and won't rust.
I wouldn't use copper in this situation. |
