How to Change the Fuel Pump in a 1998 Chrysler Town Country

The Chrysler Town & Country is a family minivan manufactured by Chrysler since 1990. It has a 6-cylinder engine with multi-port fuel injection that requires the fuel to be pressurized to about 49 pounds per square inch. The fuel pump module in the 1998 Chrysler Town & Country consists of a fuel pump and pressure regulator located in the fuel tank. You must remove the fuel tank to replace the fuel pump in this vehicle.

Instructions

1

Disconnect the cable on the negative terminal of the battery with a socket wrench to prevent sparking while you work on the vehicle. Loosen the filler cap on the fuel tank to relieve the pressure in the fuel tank. Remove the cap for the fuel pressure port on the fuel rail. Place one end of hose No. C-4799-1 into a gasoline container, and wrap a shop towel around the fuel pressure port. Attach the other end of the hose to the fuel pressure port to relieve the pressure in the fuel system. Disconnect the hose from the fuel pressure port and replace the cap.

2

Place a siphon hose into the fuel tank and drain the fuel tank into a gasoline container. Raise the vehicle with a jack and support it on jack stands. Disconnect the fuel lines from the fuel tank and fuel pump module. Slide the electrical connector for the fuel pump module to the unlock position. Push the retainer down and detach the electrical connector from the fuel pump module. Support the fuel tank with a transmission jack and remove the bolts for the mounting straps on the fuel tank with a socket wrench. Lower the fuel tank slightly so you can disconnect the filler hose from the fuel tank. Lower the fuel tank completely and remove it from the vehicle.

3

Clean the top of the fuel tank with a shop towel to prevent dirt from getting into the fuel tank. Turn the lock nut for the fuel pump module counterclockwise with tool No. 6856 and detach the lock nut from the fuel pump module.

4

Lift the fuel pump module out of the fuel tank. Remove and discard the O-ring from the fuel tank. Clean the area around the opening in the fuel tank, and install a new O-ring on the fuel tank.

5

Install the locking ring for the fuel pump module. Turn the locking ring clockwise and tighten it to 43 ft-lbs. with tool No. 6856. Install the fuel tank and connect the cable for the negative battery terminal. Fill the fuel tank with fuel and fasten the filler cap for the fuel tank. Turn the ignition on to pressurize the system and check the fuel system for leaks.
