On a duel tank pickup, it is the little "block" on the frame rail between the tanks. One of the 6-7 lines going into it is cracked and slightly leaking gas. Am I correct in thinking that the simplest way to replace it and the lines attached to it is by removing the bed of the truck to get to the lines that run to the top of each tank(both are full of gas). Does anyone have any hints or tricks to help me out with the mess I've gotten myself into by trying to replace a fuel filter?
