Solution

1. Preparation

Tools Required: OBD-II scanner, visual inspection tools (flashlight), fuel pressure gauge, smoke machine, safety goggles, gloves.
Safety Warnings: Disconnect the battery before working on electrical systems and allow the engine to cool completely before starting repairs.

2. Repair Fuel Leaks

Identify Leak Source: Based on the visual inspection and diagnostic steps, locate the exact area of the leak (fuel line, injector, or tank).
Replace Damaged Components:
- If a fuel line is damaged, cut out the affected section and replace it with a new fuel line, ensuring proper clamps are used.
- For faulty injectors, remove the affected injector using a socket set, and replace it with a new one, securing it with the specified torque (usually around 15-20 Nm depending on the model).
- If the fuel tank is leaking, you may need to replace the tank. This involves removing the rear seat, disconnecting fuel lines, and unbolting the tank.
Repair or Replace EVAP Components: If the EVAP system is faulty, replace any damaged components (e.g., charcoal canister, purge valve) with OEM parts.

3. Reassemble and Reconnect

Reinstall Components: Ensure all components are securely installed and connected.
Reconnect Battery: Reconnect the vehicle battery and ensure all electrical connections are secure.

4. Pressure Test Fuel System

Reattach Fuel Pressure Gauge: Connect the fuel pressure gauge to the fuel rail and turn the ignition to the 'ON' position (do not start the engine).
Check for Leaks: Monitor the pressure reading and inspect for any signs of leaks around connections.
