How to Replace the fuel pump on the Jeep Cherokee?

Here is a complete overview of how you can replace the fuel pump from your Jeep Cherokee without removing the fuel tank.

Step 1: Remove the rear seat

First, lower the rear seat backs and slide the rear seat forward. You’ll get access to the rear seat mounting nuts and remove them. After locating the airbag electrical connectors, disconnect them.

Then, raise the back seat and slide them backward, and from the left side rear side, remove the bolt trim cover and the bolt on it. From the center position, remove the trim cover and bolts.

For removing the rear seat, remove the headrest and get help from assistance to remove the back seat from your Jeep Cherokee. Now, you can access the fuel pump module without removing the fuel tank.

Step 2: Remove the fuel filler cap

You need to remove the fuel filler cap to release pressure from the fuel tank. For this, find out the access module, which you’ll get in the owner’s manual.

Cut the carpet from where the fuel filler cap is located. To access the fuel pump, remove the cover and disconnect the electrical connector to disable the fuel pump. For more surety, start the vehicle. If it cranks and fails to start, you successfully disable the fuel pump. Do the same task a few times.

Step 3: Disconnect the battery

Open your Jeep Cherokee hood by pressing the lever from the driver-side door. Using a flat-blade screwdriver, remove the negative terminal from the battery by loosening the cable clamp nut.

Step 4: Remove the old fuel pump

Now, you need to clean the top of the fuel pump module area to get rid of debris while doing the replacement process. Disconnect the evap and fuel delivery line connection from the top of the module. Then, use a towel to soak up any leakage fuel. 

Using large water pump pliers, loosen the secure lock ring or use a brass drift to tap the locking ring counterclockwise until it’s free. 

Then, remove the fuel pump and carefully angle the module to disconnect the transfer line at the bottom of the pump module. Then, drain out the gasoline and put it on shop rags. Then, remove the o-ring from the tank. And lay a towel above the opening of the tank to reduce fumes.

Step 5: Install the new fuel pump

Now, clean the o-ring surface and install a new o-ring on the surface. 

 Take the new fuel pump to install it, and be careful not to bend the float arm. Lower the new pump module partially into the tank and connect the transfer line to the port for installation. Then, align the locking tab and re-install the lock ring following the same method of removing.

Connect the fuel line and evap line. You’ll hear audible noise if you correctly connect them. Then, reconnect the electrical connector with the fuel pump module and install the cover. 

Then, take help from assistance and install the rear seat properly and reconnect the airbag connectors and the wiring harness. Reconnect the battery negative terminal with the battery. Now, you successfully replace the fuel pump on your Jeep Cherokee, and you’re ready to go for a test drive.
