Instructions:
1. Safety Precautions:
- Wear safety goggles and gloves.
- Disconnect the vehicle's negative battery terminal.
2. Raise the Vehicle:
- Use a car jack and jack stands to raise the vehicle.
- Ensure the vehicle is securely supported before proceeding.
3. Locate the Fuel Tank:
- The fuel tank is usually located under the rear of the vehicle.
4. Remove the Fuel Tank:
- Loosen or remove the screws holding the fuel tank in place.
- Disconnect the fuel lines and any electrical connectors attached to the tank.
- Carefully lower the fuel tank, taking care not to damage any components or spill fuel.
5. Remove the Fuel Pump Assembly:
- Locate the fuel pump assembly on the top of the fuel tank.
- Disconnect any electrical connectors or fuel lines attached to the assembly.
- Use a screwdriver or flat-head screwdriver to pry open the fuel line quick-connect couplings.
- Remove the screws or bolts holding the fuel pump assembly in place.
- Carefully remove the fuel pump assembly from the tank.
6. Replace the Fuel Pump and Filter (if applicable):
- Remove the old fuel pump from the assembly and install the new one.
- If replacing the fuel filter, do so at this time.
- Install a new fuel pump gasket.
7. Reinstall the Fuel Pump Assembly:

9. Lower the Vehicle:
- Slowly lower the vehicle using the car jack and jack stands.
10. Prime the Fuel System:
- Use a fuel injector priming tool (or pliers) to manually prime the fuel system by squeezing the fuel line that goes to the fuel injector rail.
- This will help to fill the fuel system with fuel before starting the vehicle.
11. Reconnect the Battery:
- Reconnect the negative battery terminal.
12. Start the Vehicle:
- Start the vehicle and check for any leaks or unusual sounds.
13. Test Drive:
