You want to use steel for fuel lines. Copper reacts with some of the  
compounds in modern gasoline and can cause contamination of the fuel  
system. Also, it has poor fatigue characteristics, and can crack if  
subjected to the high vibration environment of a car.

NAPA, and presumably other vendors sell lengths of 5/16" steel tubing  
that works very well for fuel line replacement. It's pretty  
reasonably priced if I remember correctly.
