Locate the fuel pump access cover on the rear seat or trunk area.
Remove the screws or clips securing the access cover.
Carefully lift the cover to expose the fuel pump assembly.

3. Disconnect Electrical Connectors

Disconnect the electrical connector from the fuel pump by pressing the release tab and pulling it off.
Ensure that the wiring harness is intact and free from damage.

4. Remove the Fuel Pump Assembly

Unscrew the retaining ring or bolts securing the fuel pump assembly to the fuel tank.
Carefully lift the fuel pump assembly out of the tank, taking care not to damage the fuel sender unit.

5. Inspect and Replace the Fuel Pump

Inspect the old fuel pump for signs of wear or damage.
If replacing, install the new fuel pump into the assembly, ensuring proper alignment.
Reassemble the fuel pump assembly and replace the retaining ring or bolts, torquing to manufacturer specifications.

6. Reconnect Electrical Connectors and Fuel Lines

Reconnect the electrical connector to the fuel pump.
Ensure all fuel lines are properly connected and secured.
