5. Lower the Fuel Tank:
- Disconnect the electrical connector to the fuel pump.
- Support the fuel tank by placing a block or jack underneath it.
- Loosen the straps or bolts securing the fuel tank and carefully lower it down.
- Be cautious as the fuel tank will still contain some fuel.
6. Remove the Fuel Pump Module:

- Use a flathead screwdriver to pry up the locking ring's tabs or remove the bolts.
- Lift the fuel pump module out of the fuel tank.
7. Replace the Fuel Pump:

10. Test the Fuel System:
- Reconnect the negative battery terminal.
- Turn the key to the "ON" position without starting the engine.

- If the pump doesn't prime, check the electrical connections and fuel lines.
11. Start the Engine:
- Start the engine and let it run for a few minutes.
- Check for any leaks or unusual noises from the fuel system.
12. Test Drive:
