Trying to replace fuel pump

you will have to raise the rear of the car then undo the fuel lines,electrical wires, vent line and the gas tank straps supporting the tank you will have to support the tank before undoing the straps, then lower the tank until you can remove the fuel tank lock ring and remove the fuel pump assembly, note that some had and extra fuel line connected to the pump assembly inside the tank and you will have to pull the pump assembly so far until you can disconnect this line. assembly in reverse order. also replace the fuel filter if its been a while.

Dependant on your model specifics, either two or one tank assembly, the tanks themselves will have a sending unit inside. You can replace just the pumps for less but you MUST exercise care when removing reinstalling and cleaning. The orig sending unit can be brittle. The plastic parts to specify. If just trying to get a truck running, start with the rear tank, and if you cannot save the tank straps you can ratchet strap the tank to the frame to make it mobile. DONT DROP THE TANK OR LET IT HANG. While under the truck lean the back side of the tank off first and it will give access to the connections you need to remove to drop the tank

Unfortunately the fuel pump is inside the fuel tank...I have found the best way to remove the pump is to take the entire bed of the truck off..the reason is the straps that hold the fuel tank up have bolts that hold the strap to the frame rail..in my experience..these bolts will snap off , leaving you more work to drill them out an so on..if you do decide to remove the bed there are 8 bolts holding it to the frame...once the bolts are removed ,you want to make sure you unplug the harness for the rear lights and also disconnect the fuel inlet assembly,then you can slide it back just far enough to gain access to the top of the fuel tank..The fuel pump assembly(also called fuel delivery module) will have a large "C" type clip holding it in.Using a screwdriver, you'll need to pop it out from around the diameter of the fuel pump. Then you may need to turn the whole pump a little to remove it...being careful of the float arm that is attached to it. Also, there are tools needed to remove the fuel lines, which should be available for rental from autozone. Be sure to replace the fuel filter as not doing this may void the warranty for the new pump. You will need the special tools for this too.
