Replacing The Fuel Pump In Your 2006 Jeep Liberty

The fuel pump in a 2006 Jeep Liberty is located inside the fuel tank and supplies pressurised gasoline to the fuel injectors in the car's engine. It is powered by a small electric motor. Fuel pumps can last for the lifetime of a vehicle but occasionally they can fail. Signs of failure include a car that won't start or stalls once it has started. A mechanic will need to access the fuel pump through an access panel in the passenger compartment or by removing the tank from the vehicle. This is a moderately complicated job and is best performed at a dealership's service department.

Disconnect the battery

Disconnecting the battery is an important first step when replacing the fuel pump in a 2006 Jeep Liberty. This is done to reduce the chance of a fire when working on the fuel pump.

To disconnect the battery, first loosen and remove the connectors from the terminals. Make sure to secure the connectors so they cannot touch the terminals. This will prevent any accidental electrical connections from being made.

It is important to note that you should only attempt to disconnect the battery if you feel confident in your abilities. If you are unsure, it is best to consult a professional mechanic or seek assistance from someone with more experience.

Once the battery is disconnected, you can proceed with the next steps of the fuel pump replacement process. Remember to exercise caution and follow all safety procedures when working on your vehicle.

Remove rear load carpet

To remove the rear load carpet of a 2006 Jeep Liberty, you will need to drill out the rivets in each corner. Once the head of the rivet is drilled off and the majority of the rivet is sticking out of the floor, use a punch to knock out the rest. You will only need to remove the two rearmost rivets to be able to pull the carpet back and gain access, but you may find it easier to remove three corners.

Remove access panel to the top of the fuel tank

To remove the access panel to the top of the fuel tank of a 2006 Jeep Liberty, you will need to first remove the rear load carpet. There are two rivets in each corner that need to be drilled out. Once the head of the rivet is drilled off, use a punch to knock out the rest of the rivet. You only need to remove the two rearmost rivets to pull the carpet back and access the panel.

Now, you will see a 10mm head nut in each corner of the panel under the sealant. Chip away the sealant with a hammer and chisel to expose the nuts. Once the nuts are removed, chip away the remaining sealant around the panel. With the nuts and sealant removed, you can now lift the access panel to the top of the fuel tank.

Remove old fuel pipes

To remove the old fuel pipes from your 2006 Jeep Liberty, you will first need to remove the rear load carpet. There are two rivets in each corner that need to be drilled out. Once the heads of the rivets have been drilled off, use a punch to knock out any remaining parts of the rivets. You only need to remove the two rearmost rivets to pull the carpet back and gain access, but you may find it easier to remove three corners.

Next, you will need to remove the access panel to the top of the fuel tank. There is a 10mm head nut in each corner of the panel, covered in sealant. Chip away the sealant with a hammer and chisel, or by any other means possible. Once the nuts are removed, chip away the remaining sealant around the panel.

With the access panel removed, you can start removing the old fuel pipes. Start with the outlet, which is the bigger of the two pipes and the one closest to the rear of the vehicle. Press both sides of the quick-connect coupling in simultaneously and pull it off, then go underneath and remove it from there.

Repeat this process for the return pipe. While it is not strictly necessary to replace both pipes, it will only take a little extra time. The only difference is that the return pipe requires 7mm ID pipe, whereas the outlet pipe requires 8mm ID pipe.

Install new hoses

To install the new hoses, first grab your new hose and slide it onto the connector on the tank. Be careful when pushing it on as the elbows on the tank are plastic and could break easily. The size of the hose you need for the outlet is 8mm in internal diameter. Before sliding it onto the tank, be sure to put your new clamp on first. Tighten the clamp, but be careful not to break the plastic elbow. Then, head underneath the vehicle, cut your hose to size, put another clamp on, and tighten it. This end connects to a metal pipe, so make sure it's tight.

Repeat the process for the return pipe. While it is not strictly necessary to replace both hoses, it is recommended to do so as it does not take much additional time. The only difference for the return pipe is that you will need a 7mm internal diameter pipe.
