Copper fuel line ??
Am doing some other work and found that the PO had installed copper line from fuel pump to carb - have never seen this before. Am concerned that there may be a down side to copper fuel line due to vibration, heat, etc.
Info or advice?

Re: Copper fuel line ??
it's been done in some old hot rods, but i'd swap for steel personally.

I have used copper on some of my old hotrods in years past but I agree with jocko. You might try the newer NiCopp line, you can bend it by hand, and another up side is that it doesn't rust..... LockDoc

Re: Copper fuel line ??
Is it actually copper, or is it NiCopp? I've used the NiCopp stuff for brakes, not fuel, but I guess it would work for that also.

I used the NiCopp for fuel line and brake lines on the '34 Ford Coupe and for fuel line and transmission coolant lines on the '67 Panel Truck with the LS1/4l60e combo, which carries 58-60 pounds of fuel pressure. It has worked great for me so far.... LockDoc

Re: Copper fuel line ??
I've installed it before on an old Dodge power wagon I owned. Had a roll of 5/16-3/8? Laying around and used it. I also sheathed it in rubber hose for road protection.
I know copper will split length wise with the line, but figured it would be a long time before that would happen. Early autos used it, internal oil lines, gas and diesel also |
