Solution

1. Preparation

Tools Required: OBD-II scanner, visual inspection tools, fuel pressure gauge, socket set, safety goggles, gloves.
Safety Warnings: Disconnect the battery before starting work on the fuel system. Ensure the vehicle is parked in a well-ventilated area.

2. Address Fuel Leak

Step 1: If a leak is found in the fuel lines or injectors, relieve the fuel pressure by removing the fuel pump relay and running the engine until it stalls.
Step 2: Replace any damaged fuel lines or seals as necessary. Use the appropriate tools to disconnect and reconnect fittings, ensuring a tight seal.
Step 3: If fuel injectors are leaking, remove the faulty injector using a socket set, replace it with a new injector, and ensure it is seated properly.
Step 4: Reconnect the fuel lines and inspect for any additional leaks before reapplying pressure.

3. Repair EVAP System

Step 1: If issues are found in the EVAP system, inspect the fuel cap for proper sealing. Replace it if damaged.
Step 2: Check and replace any damaged vent lines or hoses connected to the EVAP system.
Step 3: Clear any codes from the OBD-II scanner after repairs are completed.
