Copper Fuel Pipe

[Lloyd Barnes]

Hi all

could do with some help on fuel pipes. Have seen (I think it was one of Dave Brookes posts) that 10mm microbore copper tubing is the way to go for the fuel lines back to close by the tank, then finished off with fuel pipe.

Should I be swaging the ends of the tubing to stop the pipe blowing off and if so how? using a chevy with carb so guess not too high pressure but would rather avoid the whole thing going up in flames!

I doubt that 5 or 6 psi is enough the blow the pipes off. Just make sure that the flexible hose is a good fit and that you push it on about 30 mm. You could also use two clips as a belt and braces job.

If you insist on having some sort of end on the pipe you could get a 2mm wide piece of copper pipe and stretch it over the end of the actual copper fuel line then solder it in place. To stretch the 2 mm band you would need a bit of tapered steel rod that you can force it over.

an other option is to get a couple of bolt on fittings and crush the olives onto the pipe then remove the fittings leaving the olive behind.

I soldered on a couple of brass olives (as used in central heating plumbing etc).
Worked a treat .

Copper used to be a very popular 'rigid' fuel pipe; just be very careful that the ends which have flexibles attached are very well secured so that the movement from the flexibles cant flex the copper and fatigue it; the main reason why its not widely used anymore.

aha, never thought of using olives. thanks all, I'm sure the two clips would work but this seems like one area to be belt n braces

Hi,

I contemplated copper pipe for my brake / fuel lines but was advised by this & other forums Cunifer, (excuse the spelling) is superior in a number of ways to copper.

Cunifer - is that just copper-plated steel? Or is it a different alloy? I recall that it work hardens even quicker than copper.

"The material Cunifer is an alloy. The name is derived three principal elements copper (Cu) nickel (Ni) and iron (Fe). "
