Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.

2. Access the Fuel Pump

Remove the rear seat cushion: Pull up on the front edge to release the clips.
Remove the access panel: Unscrew the bolts securing the fuel pump access panel under the seat.
Disconnect the fuel lines: Carefully disconnect the fuel lines from the pump, using a fuel line disconnect tool if necessary.

3. Remove the Old Fuel Pump

Disconnect electrical connectors: Unplug the electrical connectors attached to the fuel pump.
Remove the fuel pump assembly: Unscrew the retaining ring and lift the fuel pump assembly out of the tank. Use caution to avoid damaging the fuel sender unit.

4. Install the New Fuel Pump

Prepare the new pump: Transfer any necessary components (like the fuel level sender) from the old pump to the new one.
Insert the new fuel pump: Place the new pump into the tank and secure it with the retaining ring.
Reconnect electrical connectors: Ensure all connectors are securely plugged in.

5. Reassemble the Vehicle

Reconnect fuel lines: Ensure all connections are tight and secure.
Reinstall the access panel: Secure with bolts.
Reinstall the rear seat cushion: Push down to reengage the clips.

6. Final Checks

Reconnect the battery: Reattach the negative terminal.
Test the fuel system: Before starting the engine, turn the ignition to the "ON" position (without starting) to prime the fuel system and check for leaks.
