Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Inspect Fuel Lines and Components

Using a socket set, remove any protective covers to access the fuel lines.
Inspect all visible fuel lines for cracks or leaks.
If any leaks are found, proceed to replace the damaged fuel lines.

3. Replace Fuel Injector Seals (if necessary)

Remove the engine cover using a socket set.
Disconnect the fuel injector electrical connectors.
Carefully remove the fuel rail with the injectors attached.
Replace the o-rings on the fuel injectors with new ones.
Reinstall the fuel rail and reconnect the electrical connectors.

4. Examine and Replace Fuel Cap (if necessary)

Inspect the fuel cap for any cracks or damage.
If the fuel cap is faulty, replace it with a new OEM fuel cap.
Ensure the cap clicks into place when installed to ensure a proper seal.

5. Inspect and Repair Fuel Tank (if necessary)

If leaks are detected from the fuel tank, support the tank with a jack and remove the mounting straps.
Lower the tank carefully and inspect for damage.
If damage is found, replace the fuel tank with an OEM equivalent.
Reinstall the tank and reconnect all lines.
