1. Preparation

Tools Required: OBD-II scanner, socket set, wrench set, fuel line disconnect tool, multimeter, safety goggles, gloves.
Safety Warnings: Disconnect the battery before starting work on the fuel system. Ensure the vehicle is in a well-ventilated area to prevent gas fumes accumulation.

2. Repair Fuel Line or Injector Leak

Sub-steps:
1. Raise the vehicle using jack stands and remove the underbody shield if applicable.
2. Locate the fuel lines and inspect for leaks. If a leak is found, mark the affected area.
3. If the leak is from a fuel line, replace it using the fuel line disconnect tool, ensuring to use the correct fuel line type and connectors.
4. If the leak is from a fuel injector, remove the injector by unscrewing it from the fuel rail and replace it with a new one, applying a small amount of engine oil on the O-rings for easier installation.

3. Replace Fuel Tank Cap

Sub-steps:
1. If the fuel cap is damaged or not sealing properly, remove it and install a new OEM fuel cap.
2. Ensure it clicks into place to create a proper seal.

4. Repair EVAP System

Sub-steps:
