I'd get it fixed so you don't waste gas.

If you want to do this yourself, you can replace it with rubber hose. Find two places where the steel line is still solid and shiny, cut it there, then do something to the ends that will prevent the hose from sliding off once it's clamped. If you have a double flaring tool for steel brake line, perform just the first step to create a bell on the ends. I've also used a flat file to make grooves around the line for the rubber hose to bite into.

If you have multi-point fuel injection, the system pressure can exceed 50 psi so be sure to use fuel injection hose and hose clamps. The hose costs a dollar per foot. There are two size clamps available. The larger one is for the supply line. On cars with a return hose to the tank, that line uses the smaller clamps. They are a band that is tightened with a bolt and nut. Don't use the common aircraft style, (worm screw clamp) as they will cut the hose over time reducing their clamping strength.

Some states do not permit replacing steel line with rubber hose even though every car uses rubber hose to go from the body to the rocking engine. In that case, bulk steel brake line works great, It can still be attached with short pieces of rubber hose on each end.
