🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel pressure

• Use the fuel pump fuse or relay method if accessible, then crank the engine briefly until it stalls.
• Turn the key off and disconnect the negative battery cable with a 10mm socket.
• Take your time here.

Step 2: Access the fuel pump module

• Fold or remove the rear seat bottom as needed using a trim panel tool.
• Lift the service cover to expose the fuel pump access area.
• Clean around the cover before opening it so dirt does not fall into the tank.

Step 3: Disconnect electrical and fuel connections

• Unplug the fuel pump electrical connector by hand.
• Use the fuel line disconnect tool to remove the fuel line from the module.
• Have a drain pan and shop towels ready for fuel drips.

Step 4: Remove the lock ring and pump module

• Use a flat-blade screwdriver and pliers only if needed to carefully release the lock ring.
• Lift the pump module straight out slowly so the float arm does not bend.
• Remove the old seal and discard it.

Step 5: Install the new pump module

• Transfer any needed parts from the old module only if the new assembly does not include them.
• Install the new fuel pump module seal in the groove.
• Set the new module into the tank in the same orientation as the old one.
• Install the lock ring and tighten it evenly. Torque to 40 Nm (30 ft-lbs).

Step 6: Reconnect lines and reassemble

• Reconnect the fuel line until it clicks into place.
• Plug in the electrical connector.
• Reinstall the service cover and rear seat parts.
• Reconnect the negative battery cable with the 10mm socket.

Step 7: Prime and check for leaks

• Turn the key to ON for 5 seconds, then OFF. Repeat 2-3 times to prime the system.
• Start the engine and inspect the fuel pump area and fuel line connection for leaks.
• If the engine does not start right away, check the connector and fuel line engagement.
