Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical hazards.

2. Inspect and Replace Fuel Lines

Inspect: Visually examine all accessible fuel lines and connections for signs of wear or leaks.
Replace: If any damaged lines are found, use the following sub-steps:
- Use a socket set to remove any brackets or clips holding the damaged line.
- Carefully disconnect the fuel line using a fuel line removal tool.
- Install the new fuel line and secure it with the appropriate clips or brackets.
- Torque the connections to the manufacturer's specifications.

3. Replace Fuel Injector O-Rings

Remove Fuel Rail:
- Disconnect the electrical connectors from the fuel injectors.
- Remove the bolts securing the fuel rail using a socket set.
- Carefully lift the fuel rail to expose the injectors.
Replace O-Rings:
- Remove the old O-rings from the injectors and discard.
- Lubricate the new O-rings with engine oil and install them on the injectors.
- Reinstall the injectors back into the fuel rail and secure it with bolts.

4. Replace Fuel Filler Cap

If the fuel filler cap is damaged or not sealing properly, replace it with a new OEM cap.
Ensure it is tightened securely to prevent vapors from escaping.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
