Best Answer

The easiest way to access the fuel pump is to remove the 8 bolts that hold the box to the frame, unplug the wiring harness for the rear lights just inside the rear bumper and have some one help you lift the box back a couple of feet and balance it on the rear tires and bumper. The top of the tank will be exposed with the fuel pump right in front of you on the drivers side. Don,t forget to change the fuel filter and wireing harness plug at the pump.
