Solution

1. Preparation

Tools Required: Safety goggles, gloves, OBD-II scanner, rags, flashlight.
Ensure the vehicle is parked on a flat surface, and disconnect the battery to prevent any electrical issues while working.

2. Fix Fuel Leaks

Sub-steps:
1. If leaks are found in the fuel lines, replace the damaged section of the line. Cut out the damaged section and install a new piece using appropriate fuel line connectors.
2. If the fuel injector seals are leaking, remove the fuel rail:
  - Disconnect the electrical connectors from the fuel injectors.
  - Unbolt the fuel rail and gently pull it away from the engine.
  - Replace the seals and reassemble the fuel rail.
3. For a damaged fuel tank, you may need to replace the entire tank if repairs are not feasible.

3. Replace Fuel Cap

If the fuel cap is damaged or not sealing properly, replace it with a new one to prevent evaporation leaks.

4. Repair Evaporative Emission Control System (EVAP)

If leaks are found in the EVAP system, replace faulty components such as the EVAP canister or purge valve as necessary.
