Solution

1. Preparation

Tools Required: Socket set, screwdrivers, fuel pressure gauge, jack and jack stands, safety goggles, gloves.
Ensure the vehicle is parked on a level surface, and the ignition is turned off.
Disconnect the negative battery cable to prevent electrical shock.

2. Relieve Fuel System Pressure

Remove the fuel pump relay from the fuse box.
Start the engine until it stalls to relieve pressure in the fuel lines.
Turn off the ignition and disconnect the negative battery cable again.

3. Access the Fuel Pump

Lift the rear of the vehicle using a jack and secure it with jack stands.
Remove the fuel tank shield (if applicable) by unscrewing the bolts or clips.
Disconnect the fuel filler neck and any vent hoses attached to the fuel tank.

4. Remove the Fuel Tank

Support the fuel tank with a jack or suitable support.
Disconnect the electrical connectors and fuel lines from the pump assembly. Use caution to avoid damaging the lines.
Remove the bolts securing the fuel tank to the vehicle.
Carefully lower the fuel tank and remove it from the vehicle.

5. Replace the Fuel Pump

Remove the fuel pump assembly from the tank by unscrewing the retaining ring.
Disconnect the old pump from the assembly and replace it with the new pump. Ensure the new pump has a new strainer attached.
Reinstall the pump assembly in the tank and secure with the retaining ring.

6. Reinstall the Fuel Tank

Raise the fuel tank back into position and secure it with bolts.
Reconnect the fuel lines and electrical connectors to the pump assembly.
Reattach the fuel filler neck and vent hoses.

7. Final Steps

Reinstall the fuel tank shield (if applicable).
Reconnect the fuel pump relay in the fuse box.
Reconnect the negative battery cable.
