How to Change the Fuel Pump on a 2003 Chrysler Minivan

The Chrysler Town & Country is a series of minivans made by Chrysler Group since 1990. The 2003 model is a member of the fourth generation, which was in production from 1991 to 1997. The most common engine in a 2003 Chrysler minivan is a 6-cylinder 3.8-liter engine that uses fuel injection to deliver fuel to the engine under high pressure. The replacement of the fuel column in this vehicle requires you to lower the fuel tank.

Instructions

1

Disconnect the cable for the negative battery terminals with a socket wrench to ensure that you dont start the engine accidentally during the fuel pump replacement. Open the filler cap of the fuel tank to release the pressure in the fuel tank. Remove the protective cap for the fuel pressure test port on the fuel rail.

2

Place one end of hose no. C-4799-1 into a container approved for gasoline and wrap a shop towel around the test port. Connect the open end of the hose to the test port to relieve the pressure in the fuel system. Remove the hose from the test port and replace the cap for the test port.

3

Insert one end of a hose into the fuel tank and place the other end into the gasoline container. Siphon as much fuel from the fuel tank as possible.

4

Support the fuel tank with a jack and remove the bolts for the fuel tank strap with a socket wrench. Remove the fuel tank straps and fuel lines from the fuel tank. Detach the electrical connector for the fuel pump. Lower the fuel tank with the jack to gain access to the fuel pump.

Turn the locking ring for the fuel pump module counterclockwise with a socket wrench. Remove the locking ring from the fuel pump module and disconnect the fuel pump module from the fuel tank.

6

Connect the new fuel pump module to the fuel tank and place the locking ring on the fuel pump module. Tighten the locking ring to 40 ft. lbs. by turning it clock wise with a torque wrench. Connect the electrical connector for the fuel pump module and attach fuel lines for the fuel tank. Install the fuel tank and tighten the bolts for the fuel tank straps to 40 ft. lbs.
