🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel system pressure

• Use the proper service method to remove fuel pressure from the system before disconnecting anything.
• If the vehicle has a fuel pump relay or fuse service step, follow that first.
• Do this before opening the tank.

Step 2: Disconnect the battery and raise the vehicle

• Use a wrench or socket to disconnect the negative battery cable.
• Raise the vehicle with the floor jack and support it on jack stands.
• Make sure the vehicle is stable before working underneath it.

Step 3: Remove the fuel tank shield and nearby components

• Use the metric socket set and ratchet to remove any underbody shields or braces blocking the tank.
• Disconnect the EVAP lines and electrical connector(s) as needed.

Step 4: Disconnect the fuel filler neck and lines

• Use the flat-blade screwdriver and pliers if hose clamps or retainers must be released.
• Use the fuel line disconnect tool to remove the fuel line from the tank module.
• Cap or cover open lines to keep dirt out.

Step 5: Lower the fuel tank

• Support the tank with the floor jack.
• Use the metric socket set and ratchet to remove the tank strap bolts.
• Lower the tank slowly and check for any remaining connectors or hoses.
• Disconnect any remaining wiring or vent hoses, then lower the tank fully.

Step 6: Remove the fuel pump module

• Clean the top of the tank before opening it so dirt does not fall inside.
• Use the flat-blade screwdriver or the correct lock ring removal method to release the pump module retaining ring.
• Lift the fuel pump module out carefully and avoid bending the float arm.
• Remove the old fuel tank seal/O-ring.

Step 7: Install the new fuel pump module

• Install the new fuel tank seal/O-ring in the clean groove.
• Lower the new pump module into the tank in the same orientation as the original.
• Install the retaining ring and tighten it to factory specification for the fuel pump module lock ring.
• Do not pinch the seal.

Step 8: Raise the tank and reconnect everything

• Raise the tank with the floor jack and reconnect all hoses, lines, and wiring.
• Install the tank straps using the metric socket set and tighten the bolts to factory specification for the tank strap fasteners.
• Reinstall any shields or braces removed earlier.

Step 9: Prime and inspect

• Reconnect the negative battery cable.
• Cycle the key to ON for a few seconds, then OFF, several times to prime the system.
• Check all fuel lines and the tank area for leaks before starting the engine.
• Start the engine and verify smooth running.

✅ After Repair

• Inspect for fuel leaks with the engine running and after shutoff.
• Check for fuel pressure-related hard starts or stalling.
• Take a short road test and confirm normal acceleration.
