You have a separate fuel level sensor in the tank aslo,as well as the fuel pump modual if your going to be in there may as well do the whole unit as one,quick tip on doing the fuel pump just move the bed back about two feet,pick it up and let the front part rest on the tires and the back part can rest on the bumper,very easy to get to the pump without having to drop the tank.lets see i think there's 4-6 bolts holding the bed on frame,3 torx holding filler neck to bed and the ground is right around that area and i think all you have to do is remove the tag light bulbs with wiring let them hang out of the way.If i remember right thats all there is to removeing the bed.somebody add if i missed something
