There is only one fuel line. If you look close the other line is a plastic cover over theelectrical
lines going to your fuel pump (which is just ahead of your fuel filter). You can get barbed hard plasic couplings that will slip into the rubber hose (after you have cut the fuel line in half). Put two new fuel line clamps on each side of the barbed coupling. The rubber fuel hose would be a lot of trouble to replace from the tank to the filter.
Oh by the way: You will want run your fuel way down before you fix this leak. When you take that line loose or cut it the fuel in your tank is going to drain out through that hose. You will want to catch this fuel in a container of some sort.
