Places like Autozone and NAPA sell replacement sections of fuel lines, usually they are the end sections with the quick connect fitting on the end and they are about 3 feet long. They come with a metal insert that you push into the fuel line and then you push the new peice over the other end of this insert. They fit really tight and seal up fine. I had to replace one on my sons Bronco II fuel supply line after I broke it taking the tank out and it didn't leak a drop, and the fuel pump on the truck was operating at about 50 psi. You just need to know the correct diameter of the line, or take a chunk of it with you.
