What You'll Learn
The fuel filter is inside the tank
The fuel filter in a 2000 Jeep Grand Cherokee is located inside the tank. This model is also known as the Jeep WJ. The fuel filter is part of the fuel pump assembly, which is situated inside the tank.
To access the fuel filter, you will need to remove the fuel pump assembly. This process involves the following steps:
- Siphon the gas out of the tank to lower the fuel level and gain better access to the assembly.
- Locate the fuel pump assembly inside the tank.
- Detach the assembly by removing any necessary bolts or connectors holding it in place.
- Carefully lift or slide out the fuel pump assembly, being mindful of any attached hoses or wiring.
Once the fuel pump assembly is removed, you will be able to locate the fuel filter attached to it. The fuel filter may be integrated into the assembly or connected to the fuel pump itself.
It is important to note that some sources suggest that the fuel filter may not be easily visible inside the tank. It may be attached to the pump, sitting just above the bottom of the tank. Therefore, when removing the fuel pump assembly, pay close attention to the pump and its surrounding components to locate the fuel filter.

Disconnect the blue and white connectors
To disconnect the blue and white connectors on a 2000 Jeep Grand Cherokee, you will need to locate the fuel filter. The fuel filter on this model is remotely mounted to the vehicle body, above the rear axle, and near the front of the fuel tank.
