How to locate the fuel filter panel
To locate the fuel filter panel on a Jeep Liberty, you will need to raise the vehicle's hood and locate the fuse panel. Remove the plastic cover using a screwdriver, and then remove the fuse that controls the fuel pump. Start the vehicle and allow the motor to idle. The Jeep will stall out after a few seconds, clearing the fuel line of excess fuel.
The fuel filter panel is located under the rear of the Jeep, between the fuel tank and the rear driver's side tire. You will need to access the filter from underneath, once the fuel lines are off. Put a drain pan under the fuel filter, as there is a third fuel line attached to the bottom of the filter. The disconnection point for this line is about one foot towards the front of the vehicle.
For the earlier models of the Jeep Liberty, there is an access panel under the carpet in the rear. You will need to release the fuel pressure and have a fire extinguisher on hand, as you will be working with open fuel.
