How to Install the Fuel Pump on a 1997 Dodge Ram

The Dodge RAM is a series of pickup trucks in a variety of carrying capacities and trim levels. The 1997 models use multi-port fuel injection to deliver fuel to the engine under high pressure. The fuel pump in these vehicles is part of a module that also includes the fuel gauge sending unit and float. The fuel pump module in a 1997 Dodge RAM is attached to the top of the fuel tank, so you must disconnect the fuel tank to install a new fuel pump.

Instructions

1

Disconnect the negative battery cable with a socket wrench to ensure you dont inadvertently attempt to start the engine. Open the filler cap for the fuel tank to relieve the pressure in the fuel tank and remove the cap from the fuel pressure port on the fuel rail.

2

Attach a fuel pressure gauge to the fuel pressure port and place the open end of the pressure gauges hose into a gasoline container. Open the pressure gauge to relieve the fuel pressure in the fuel system. Remove the pressure gauge from the fuel pressure port and replace the cap.

3

Pump the fuel from the fuel tank into a gasoline container with a hose. Raise the vehicle with a floor jack and support it with jack stands. Disconnect the fuel line and electrical connection from the fuel gauge unit. Remove the mounting screws for the filler tube assembly with a socket wrench and disconnect the filler tube from the fuel tank.

4

Support the fuel tank with a transmission jack and remove the nuts for the fuel tanks mounting straps. Lower the tank slightly with the transmission jack so you can detach the fill hose and vent hose to the fuel tank. Remove the electrical connections for the fuel tank. Disconnect the evaporative emissions line and the fuel supply line. Remove the fuel tank from the vehicle.

5

Disconnect the fuel line to the fuel pump module. Clean the fuel tank around the fuel pump module with the shop towel to ensure that debris doesnt fall into the fuel tank when you replace the fuel pump.

6

Turn the locking ring for the fuel pump module counterclockwise with a socket wrench. Remove the locking ring from the fuel pump module, and clean the fuel filter at the bottom of the fuel pump module. Discard the gasket for the fuel pump module.

7

Install the new fuel pump module and its gasket by performing steps three through six in reverse. Tighten the locking ring for the fuel pump module to 40 ft-lbs. with a torque wrench. Fill the fuel tank with fuel and connect the negative terminal for the battery with a socket wrench.
