Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Repair Fuel Leaks

Tools Required: Socket set, wrenches, fuel line removal tool.
Check the fuel lines and connections for leaks. If a leak is found:

- Replace any damaged sections of the fuel line with new, OEM-specified line.
- Reconnect the line, ensuring all connections are secure.

3. Replace Faulty Fuel Injector (if necessary)

Tools Required: Socket set, fuel injector puller.
If a fuel injector is leaking:
- Disconnect the electrical connector from the injector.
- Remove the retaining clips and pull the injector out of the rail.
- Replace with a new injector, ensuring to lubricate the O-rings with clean engine oil.
- Reinstall the injector and reconnect the electrical connector.

4. Check and Replace Fuel Tank (if damaged)

Tools Required: Jack and jack stands, socket set.
If the fuel tank is damaged:
- Safely lift the vehicle using a jack.
- Disconnect the fuel lines and electrical connectors from the tank.
