2. Check for visible leaks or cracks along the fuel lines.
3. If damage is found, remove the affected section of the fuel line using a socket set.
4. Replace with new fuel line sections, ensuring proper fittings are used.
5. Tighten connections securely (typically 10-15 ft-lbs torque).

3. Replace Fuel Injectors (if needed)

Sub-steps:
1. Remove the engine cover (if applicable) to access fuel injectors.
2. Disconnect the electrical connectors from each fuel injector.
3. Remove the fuel rail bolts and gently lift the rail to access injectors.
4. Replace any leaking injectors with new ones, ensuring O-rings are properly seated.
5. Reassemble the fuel rail and reconnect electrical connectors.

4. Check EVAP System

Sub-steps:
1. Locate the EVAP canister and purge/vent valves.
2. Inspect for cracks or damage in hoses connected to the canister.
3. Replace any faulty valves or hoses.
4. Clear any error codes from the OBD-II scanner after repairs.

5. Inspect and Replace Fuel Cap

Sub-steps:
1. Check the fuel cap for cracks or damage.
2. If found defective, replace it with a new OEM fuel cap.
3. Ensure it is tightened properly to create a good seal.
