How to Install a Lift Pump on a 2004 Dodge Ram 3500
The Dodge Ram series of full-size pickup trucks is manufactured by Chrysler under its Dodge brand. The 3500 models have a rated carrying capacity of 3/4 ton, although the actual carrying capacity is higher than this. The 2004 Dodge Ram 3500 with a diesel engine uses a fuel lift pump (transfer pump) to move fuel from the fuel tank to the fuel system. The fuel lift pump on this vehicle attaches to the rear of the fuel filter.
Instructions
- 1
Place a gasoline container under the fuel filter separator and turn the drain plug on the bottom of the separator in a counterclockwise direction. Drain the fuel from the fuel filter and tighten the drain plug.
2Detach the electrical connector on the fuel lift pump. Disconnect the fuel line for the fuel lift pump from the inner left frame rail.
3Remove the mounting bolts for the fuel lift pump from the fuel filter, using a hex wrench.
Discard the O-ring in the housing of the fuel filter.
4Mount a new O-ring on the fuel lift pump, then coat the O-ring with a thin layer of new engine oil. Place the fuel lift pump into position so that it is flush with the fuel filter housing. Fasten the mounting bolts for the fuel lift pump, and tighten them to 61 inch-pounds, using a torque wrench.
5Connect the fuel line to the connection on the inner left frame rail. Attach the electrical connector for the fuel pump.
6Turn the ignition on for two seconds to prime the fuel system, then check for fuel leaks. Start the engine and check again for fuel leaks.
