fuel delivery problem

My truck has a fuel leak on the driver side tank (dual tank truck).It's not the tank rusting because it only leaks when i flip the switch to left tank. What tends to rot out/leak more: the supply line, the return line, or the left side input of the mechanical part of the switch?

Re: fuel delivery problem

It sounds like the one of the rubber hoses on top of the tank is cracked or busted.

Re: fuel delivery problem

To me it sounds like the return line. Easy way to check it to plug the return line off at the valve coming back to the tank (smaller line) and see if it stops leaking then.
