🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel system pressure

• Open the fuse box and remove the fuel pump fuse using your fingers or needle-nose pliers.
• Start the engine and let it run until it stalls. Crank for a few more seconds to bleed off remaining pressure.
• Turn the key off and reinstall the fuse after pressure is relieved.

Step 2: Disconnect the battery

• Use a 10mm socket to disconnect the negative battery cable.
• Move the cable aside so it cannot spring back and touch the terminal.

Step 3: Remove the rear seat cushion

• Pull up sharply on the front edge of the rear seat cushion to release the retaining clips.
• Lift the cushion out of the car.
• Keep the clips in a safe place.

Step 4: Remove the fuel pump access cover

• Use a flat blade trim tool to lift the access cover in the floor.
• Remove the cover and set it aside.

Step 5: Unplug the fuel pump and lines

• Use your fingers to disconnect the electrical connector from the fuel pump module.
• Use the fuel line disconnect tool if the quick-connect line is tight.
• Place a drain pan and shop towels under the lines to catch any fuel.

Step 6: Remove the fuel pump lock ring

• Use a brass drift or suitable non-sparking tool and a hammer to rotate the lock ring counterclockwise.
• Lift the lock ring off the tank opening.
• Do not use steel tools that can spark.

Step 7: Remove the fuel pump module

• Carefully lift the module straight up and out of the tank.
• Tilt it slowly so the float arm clears the opening.
• Let excess fuel drain into the tank opening or a fuel-safe container.

Step 8: Install the new module

• Transfer any needed parts only if your replacement requires it.
• Install the new fuel pump module gasket / seal into the tank opening.
• Lower the new module into the tank carefully.
• Make sure the float arm is not bent or trapped.
• Install the lock ring and tighten it evenly to factory specification.

Step 9: Reconnect lines and wiring

• Reconnect the fuel line until it clicks into place.
• Reconnect the electrical connector.
• Double-check that the line is fully seated.

Step 10: Reinstall the access cover and seat

• Reinstall the access cover.
• Set the rear seat cushion back in place and press down until the clips lock.

Step 11: Restore power and prime the system

• Reconnect the negative battery cable using the 10mm socket.
• Turn the key to ON for 5 seconds, then OFF.
• Repeat this 3 times to prime the fuel system.
• Start the engine and check for leaks.
