- Remove the engine cover if necessary.
- Disconnect the electrical connector from the faulty injector.
- Remove the fuel rail bolts and gently lift the rail to access the injectors.
- Replace the faulty injector with a new one, ensuring proper sealing.
- Reassemble the fuel rail and reconnect all electrical connectors.
Fuel Tank Repair/Replacement:
- If the tank is damaged, remove it by draining fuel and disconnecting all attached hoses and electrical connectors.
- Replace with a new tank if necessary, following the manufacturer’s installation instructions.
Fuel Pump Replacement:
- Access the fuel pump through the access panel or by removing the tank.
- Disconnect the fuel lines and electrical connectors.
- Remove the pump assembly and replace it with a new one.
- Reinstall everything in reverse order.

4. Reconnect Components

Reconnect the battery.
Start the engine and check for leaks around the repaired areas.
Ensure all components are functioning properly.
