What's wrong with copper fuel lines?
I watch 'American Hot Rod' on TV and Boydd's shop built with copper fuel lines, so it must be the right thing to do

If you use copper, make sure you always know where the fire station is

Get rid of the copper line. It has very little fatigue resistance to vibration and will crack. Use rubber line ONLY to connect 2 hard lines (about 2" max at each connection) and replace the rubber periodically.
