Copper Fuel Line

I'm doing an EFI swap on a 64 F100. I was planning on using the existing fuel line on the truck at the drain line. When I got under the truck and started working I found someone replaced the original line with a copper line. Is there any issues reusing this copper line for the fuel return?

Re: Copper Fuel Line

Copper tends to work harden under continuous movement and vibration, making it susceptible to cracking.  SAme with aluminum.
I would advise steel line with AN or SAE inverted flare fittings.
