1. With the engine turned OFF , relieve the fuel pressure at the pressure regulator. Refer to the fuel relief procedure in this section.
2. Disconnect the negative battery cable.
3. Raise and support the rear of the vehicle on jackstands.
4. Drain the fuel tank, then remove it.
5. Using a hammer and a drift punch, drive the fuel lever sending device and pump assembly locking ring (located on top of the fuel tank) counterclockwise. Lift the assembly from the tank and remove the pump from the fuel lever sending device.
6. Pull the pump up into the attaching hose while pulling it outward away from the bottom support. Be careful not to damage the rubber insulator and strainer during removal. After the pump assembly is clear of the bottom support, pull it out of the rubber connector.

1. Connect the fuel pump to the hose.

Be careful that you don't fold or twist the strainer when installing the sending unit, or you'll restrict fuel flow.

1. Install a new O-ring on the pump assembly and then position them into the fuel tank.
2. Turn the locking ring clockwise until its tight.
3. Install the fuel tank and connect the battery cable.

If you dont feel like dropping the tank and hassling with the hangers because they often break cut a hole in the bed of your truck over the tank where the fuel pump is but be careful not to hit the wires. dont cut the piece out completely cut it so you can pry it up to oneside

Pull fuel tank. Some people unbolt bed and lift with floor jack.
