🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect the 12V battery

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

Step 2: Relieve fuel pressure

• Remove the gas cap slowly to release any vapor pressure.
• Work slowly to avoid fuel spray.

Step 3: Remove rear seat or access trim

• Use a trim panel removal tool and 10mm socket to remove the rear seat lower cushion or access trim, depending on the access layout.
• Lift the trim carefully to expose the fuel pump service cover.

Step 4: Remove the fuel pump access cover

• Use a Phillips screwdriver or 10mm socket to remove the access cover fasteners.
• Lift the cover and peel back the sealing material carefully.
• Keep dirt away from the opening.

Step 5: Disconnect the fuel pump electrical connector and fuel line

• Use a flat-blade screwdriver or your fingers to release the connector lock.
• Use the fuel line disconnect tool to disconnect the fuel supply line.
• Wrap the line with shop towels to catch any fuel drips.

Step 6: Remove the fuel pump lock ring

• Use the lock ring tool (specialty) to rotate the retaining ring counterclockwise.
• Lift the ring off once it is free.
• Do not strike the ring with metal tools.

Step 7: Remove the fuel pump module

• Carefully lift the fuel pump module straight up and out of the tank.
• Use a shop towel to catch fuel from the module.
• Note the float arm position so the new unit goes back in the same orientation.

Step 8: Install the new seal and fuel pump module

• Use a new fuel pump seal / tank gasket on the tank opening.
• Lower the new pump module straight into place.
• Make sure the locating marks line up correctly.
• Install the lock ring with the lock ring tool (specialty).
• Torque to manufacturer specification for the lock ring if available from your service data.

Step 9: Reconnect the fuel line and electrical connector

• Reconnect the fuel line until it clicks fully into place.
• Reconnect the electrical connector and confirm the lock is seated.
• Inspect the line routing to be sure nothing is pinched.

Step 10: Reinstall the access cover and interior trim

• Use a 10mm socket or Phillips screwdriver to reinstall the access cover.
• Replace the sealing material if it was damaged.
• Reinstall the seat cushion or trim panels with the trim panel removal tool.

Step 11: Restore battery power and prime the system

• Use a 10mm socket to reconnect the 12V battery negative terminal.
• Turn the ignition ON without starting the vehicle for 5 seconds, then OFF.
• Repeat this 2-3 times to prime the fuel system.

Step 12: Check for leaks and start the engine

• Start the vehicle and let it idle.
• Inspect the pump area and fuel line connection for leaks.
• If you smell fuel, shut it off immediately and recheck the seal and line connection.
