I just went threw this. Truck did the same thing for about a year and then the fuel pump went out at the gas station and had to have it towed. You need to change the fuel pump and the fuel filter. Not to hard. The best way is to take the bed off. It is held on by 8 bolts. Make sure you open the filler neck door and take the 3 hex bolts that hold the filler neck in place. Then disconnect the tail light connecting plugs in the rear right in front of the rear bumper. There will be a small black ground wire connected to the frame should be on the passenger side if I remember correctly, either way passenger or driver side remove it from the frame. Before you slide the bed back be sure to pull the spare tire sleeve out of the rear bumper. It is housed in a small rubber gromet that comes out beside the licsense plate. Then just get 2 or 3 buddies to help you slide it back about a foot and you should be able to see the top of the fuel tank. Once you get the metal ring that holds the fuel pump in place off the pump and the sending unit will come out as one. They are all one unit. A flat head screw driver and a hammer work well on getting the ring to slide out. Once you have removed the old pump and sending unit, put the new in. This thing is spring loaded so you will have to have someone push real hard down on the new pump while you slide the retainer ring back into its grooves. There should be some pretty good instructions with the new pump on how to do this. GOOD LUCK.
