Solution

1. Safety Preparation

Ensure the vehicle is on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical sparks.
Allow the engine to cool down before proceeding.

2. Locate the Leak

Fuel Lines: Examine the entire length of the fuel lines for any signs of leakage. If a leak is found, mark the area for repair.
Fuel Tank: Inspect the fuel tank for any cracks or corrosion that might cause leaks.

3. Repair or Replace Damaged Components

Fuel Lines:
- If a fuel line is damaged, use a wrench to disconnect it at both ends.
- Cut the damaged section out and replace it with a new piece of fuel line, ensuring it meets OEM specifications.
- Use appropriate clamps to secure the new line at both ends.
Fuel Tank:
- If the tank is damaged, remove it by draining the fuel and disconnecting the fuel lines and electrical connections.
- Replace the tank with a new one, ensuring to reattach all connections securely.

4. Inspect and Replace Fuel Injectors (if necessary)

Remove the fuel rail using a socket set and carefully take out the fuel injectors.
Inspect O-rings for wear; replace if necessary.
Reinstall the fuel injectors and the fuel rail, ensuring all connections are tight.

5. Final Checks

Reconnect the battery terminal.
Turn the ignition to the on position (without starting the engine) to pressurize the fuel system and check for leaks.
If no leaks are present, start the engine and monitor for any signs of leakage.
