1. Locate the fuel lines running from the fuel tank to the engine.
2. Use the socket set to remove any protective covers.
3. Check for cracks or wet spots on the fuel lines.
4. If leaks are found, replace the damaged sections with new fuel line segments using the fuel line disconnect tool.
5. Re-torque all connections to manufacturer specifications.

3. Examine Fuel Injectors and Rail

Sub-steps:
1. Locate the fuel rail and injectors on the engine.
2. Inspect for any signs of fuel leakage around the injectors.
3. If leaking, replace the faulty injector(s) following the manufacturer's specific torque specifications.
4. Clean the fuel rail and reinstall it if it was removed for access.

4. Inspect EVAP System

Sub-steps:
1. Locate the charcoal canister and inspect for cracks or damage.
2. Check all hoses connected to the canister for blockages or wear.
3. Replace any faulty hoses or canister as necessary.
4. Ensure the system is properly sealed to prevent vapor leaks.
