Solution

1. Preparation

Tools Required: Safety goggles, gloves, OBD-II scanner, socket set, torque wrench, fuel pressure gauge, smoke machine.
Ensure the vehicle is parked in a well-ventilated area and the engine is cool.

2. Repair Fuel Leaks

Locate the Leak: If a leak is found during the visual inspection, identify the source (fuel line, injector, etc.).
Replace Damaged Components:
- For fuel lines: Disconnect the battery. Use a socket set to remove any brackets holding the line, then replace the damaged section with a new line. Tighten connections to manufacturer specifications.
- For fuel injectors: Disconnect the fuel line and electrical connector. Remove the injector using a socket set. Install the new injector, ensuring O-rings are lubricated. Reconnect the fuel line and electrical connector.

3. Repair EVAP System Issues

Replace Faulty Components:
- If the charcoal canister or purge valve is faulty, disconnect the battery. Remove the canister or valve using a socket set. Install the new component, ensuring all connections are secure.

4. Reassemble and Test

Reconnect the battery and clear any error codes using the OBD-II scanner.
Start the engine and check for any signs of leaks or issues.
