Hey guys, Have heard that you can and cant use copper for fuel lines? Does it react or whats the go? I need to use a little (30cm) half inch hard line in my fuel system and am having problems locating some. I dont want to buy a whole roll. Anyone have any ideas on where to get the correct hard line or if copper is fine? Thanks

Quote: Copper works. It was used for years in the early days of cars. Steel is used now because it is cheeper. You could also used aluminum, no problem there either That was Taken off a search in google. I'd try and use steel.

Im only using it between the surge tank and fuel pumps so only a really small section. Ill give it a go.

Copper is just as strong as aluminium in fuel lines and the vl has aluminium lines from factory not steel. Strength is no issue when the lines are attached to the body of the car since it wont be moving or stressed. Ive only ever seen copper fuel lines on old hot rods and they clear coated them so the copper doesnt go dull, looks cool but unaware if its a good idea or not .

Copper is more sensitive to vibration then aluminium and steel and will have a hardening affect on it and will eventually crack. I'd be using steel or aluminium

youll be fine with copper in terms of durability and cracking iv seen copper pipes take a good beating and still havent failed as a fuel line it should be fine

The stuff you want is called bundy tube. Not sure if you can get in 1/2" though. Try Enzed, pirtek, etc.

try the thicker walled copper pipe... and again, why not use braided or rubber?

because they can become stiff, brittle and incredibly hard to remove when using some fuels my car was running methanol when i bought it, all rubber section of my fuel lines were shot, they were all stuck to everything and was no chance i could get them off without cutting them down the side. im sure you can get specific rubber for specific fuels though... copper is just an oldschool thing Some original photos have not been recovered yet.

ahh i see, well yea youcan get rubber thhat is compatible with methanol etc, i know that silicone lines dont go hard when used with methanol try sourcing out a rubber fuel line with a silicone inner layer?

i ran 1/2' alloy pipe for my cousins old chevy, boot to motor. ill brake it down how i did it, tank to filter 200mm braided line and speed flow fittings, filter to pump 200mm briaded line and speed flow fittings. pump to second filter 2 meters or so alloy pipe, speed flow bush and compresion type fittings, second filter to twin in let carby set up 500mm briaded line and speed flow fittings i cant see a problem wih copper unles it reacts with unleaded fuel ? dunno but id say no. refridgearnt copper is thicker wall but you'll need to aneal the coper befor you bend it (this is a must with thicker walled copper - cause it you dont it will be weakend if not split) you could try normal hard drawn copper but you'll need to use benders could become a pain under a car. if you use anealed copper coil it will be much easyer and once set in place over time with become hard drawn from vibriations, the one thing with copper is if its under the car in places it will get wet use a bit of plastic rubber or duct tape to any secton of copper touching the metal on the car, as it may rust....
