Copper Fuel Line?

[quick60]

Thisi s really a two question post.

1. Can copper fuel line be plumbed from the fuel pump to carb on a daily driver? I saw a show featuring one of Jay Lenos cars and it had all copper tubing everywhere and it looked cool as could be. Thought I'd try it.

2. Bought a flaring tool at an estate sale. Didnt come with any adaptors that I saw on a youtube flick on double flaring. Do i need to get adaptors to make this tool usable When I say adaptors I mean these hardened steel discs that actually inserted in the tubing and they pushed on to make the flare. I have the tool you clamp the various size tubing in then the part that screws down to make the flare.

Any help or reference to how to on this subject would be cool.

THANKS!!!!!

You can prolly buy those inserts from Sears--just look up a kit of theirs that has them and order the inserts as "replacement parts" for that kit.

Copper doesn't play nice with some other metals.

For instance, a customer had an aluminum storm door below a section of copper guttering. When the gutters overflowed, they splashed down on the storm door. The water from the gutter disintegrated the aluminum on the storm door. It looked like it rotted away!


If the entire fuel system were made from copper, it wouldn't be as much of a problem...with the exception of the t hardening.

I've been using copper for my fuel line (from the pump to the carb) for the past 5 years with no issues. I've even had to re-work it a couple of times (shorten it), but there haven't been any leaks or cracks. I've also only used a single flare on the ends, not a double flare.

1) fuel lines from pump to carb will be single flare, so no, you don't need the added pieces for double flaring with your tool.

2) regardless of whether folks get away with it or not, copper line shouldn't be used anywhere that it is subject to vibration. It will work harden and eventually crack. How long until that happens is hard to say, but copper is very prone to work hardening from vibration. For instance, its strictly prohibited in any aircraft installation for this reason.

i had a graham they had copper brake lines from the factory

Been using it with my 68 & 56 for many, many years. No problems. I even polish it up before a car show so it looks nice.

With the high heat absorption of copper the fuel should be near the boiling point by the time it reaches the carb. If you have any excess horsepower hot fuel will take care of it right away. And if it should break or spring a leak then that is just job security for the Tx Firefighter.

coming in on the end of this but was the Leno car a steam car? a lot of his old stuff is and that would make more sense wouldn't it to have cooper as plumbing for a boiler than use it in an automotive applacation? Jim
