How to Change the Fuel Filter on a 1989 Jeep Cherokee

The Jeep Cherokee uses an in-line fuel filter to protect the engine from any debris and sediment that may have gotten in to the fuel lines. The fuel pump picks up fuel from the fuel tank and sends it through the fuel lines to the engine. There is a strainer located by the pump that catches most of the debris. The smaller pieces of debris and sediment get past the strainer and are suctioned through the pump. The fuel filter is responsible for pulling this debris out of the lines.

Tools Used: Socket wrench, Socket set, New fuel filter

Change the Fuel Filter

Open the hood to access the engine compartment. Locate the fuse panel behind the battery. Open the fuse panel by releasing the clips to the side of the panel. Locate the relay that is labeled " fuel pump." The relay will be the last relay on the panel. Pull it out with your fingers. Start the jeep and allow it to run until it stalls. This will relieve the pressure in the fuel line.

Locate the fuel filter under the jeep. It is located toward the center of the vehicle.

Pull the tab up on the quick-disconnect fitting where the fuel line meets with the filter and pull away from the filter. Repeat for the other side of the filter.

Unbolt the filter from the mounting bracket with a socket wrench. Pull the filter away from the mounting bracket.

Place the new filter into the mounting bracket. Ensure it is positioned the same as the previous filter.

Push the fuel lines onto the filter until they lock in place.

Insert the fuse relay for the fuel pump back into the fuse box. Lock the cover back over the fuse box.

Turn the ignition key and allow it to sit in the start position for five seconds. This will prime the fuel pump. Turn the key to start the Jeep. The Jeep may take longer to start as the fuel pump needs to push fuel through the lines. Allow the Jeep to idle for five minutes. Inspect the fuel filter for leaks while the Jeep is running.

Tips & Warnings

Placing a small drain pan under the fuel lines will catch any excess fuel that may still be in the fuel lines.

Use caution when working around gasoline as it is very toxic and flammable.
