Solution

1. Preparation

Tools Required: Safety glasses, gloves, shop towels, OBD-II scanner.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace Fuel Lines

Locate the fuel lines running from the fuel tank to the engine.
Check for cracks, abrasions, or loose connections.
If leaks are found:
- Use a wrench to disconnect the damaged line.
- Replace it with a new fuel line, ensuring it meets OEM specifications.
- Tighten connections to manufacturer torque specifications.

3. Check and Replace Fuel Cap

Inspect the fuel cap for any signs of damage or wear.
If the cap is not sealing properly:
- Remove the old fuel cap.
- Install a new fuel cap, ensuring it clicks into place and seals correctly.

4. Inspect and Replace Fuel Injectors (if needed)

Remove the engine cover to access the fuel injectors.
Check for fuel leaks around the injectors.
If leaking:
- Disconnect the fuel injector electrical connector.
- Remove the retaining clips and pull out the injector.
- Replace it with a new injector, applying a small amount of lubricant to the O-ring for proper sealing.
- Reinstall the retaining clips and reconnect the electrical connector.

5. Inspect and Repair EVAP System

Locate the EVAP canister and associated hoses.
Inspect for cracks, disconnections, or blockages.
Replace any damaged hoses and ensure all connections are tight.
