How to Replace the Fuel Pump on a 1998 Dodge Pickup
The Dodge RAM series of full-size pickups includes several specific models. The procedure for replacing the fuel pump in a Dodge pickup truck is generally the same for all model years from 1997 to 2000. These vehicles use an electric fuel pump module that consists of the pump, fuel gauge sending unit and the fuel float. The fuel pump module is located on top of the fuel tank, so you must remove the fuel tank to replace the fuel pump module.
Instructions
- 1
Relieve the pressure in the fuel system, and remove the fuel from the fuel tank. Disconnect the fuel tank from the vehicle, and disconnect the fuel lines from the fuel pump.
2Clean the surface of the fuel tank around the fuel pump module to prevent debris from falling into the tank when you remove the fuel pump module. Locate the alignment mark on the fuel pump module, and note its position for future reference. Two door models generally have the alignment mark on the fuel pump module at the 7 oclock position, and four door models generally have the alignment mark at 4 oclock position.
3Apply a thin layer of lubricant to the fingers and finger locks of the fuel pump module if it is so equipped. Pry back the lock tab of the fuel pump module with a screwdriver if it is so equipped. Remove the locknut of the fuel pump module with a socket wrench. Remove and discard the old fuel pump module and gasket.
4Clean the fuel filter, and install the new gasket. Install the new fuel pump so the alignment mark is in the position that you noted in step 2. Tighten the locknut until it locks into place if it has fingers and finger locks. Otherwise, tighten the locknut to 40 ft. lbs. with a torque wrench.
5Connect the fuel lines to the fuel pump, and install the fuel tank. Fill the tank with fuel and pressurize the fuel system by turning the ignition on and off several times.
