Fuel Lines:
- Visually inspect fuel lines for cracks or holes.
- If damaged, use a socket set to remove the old fuel line.
- Install a new fuel line, ensuring proper routing and secure connections.
Fuel Tank:
- If a leak is found in the fuel tank, remove the skid plate (if equipped) using a socket set.
- Drain the fuel tank to a safe level.
- Replace or repair the fuel tank as necessary.
Fuel Injectors:
- Remove the engine cover (if applicable) to access fuel injectors.
- Use a socket set to disconnect the fuel injector harness.
- Replace faulty fuel injectors with new ones, ensuring a proper seal.

3. Reassemble and Test

Reattach any components removed during inspection.
Reconnect the negative battery terminal.
Start the engine and allow it to idle while checking for leaks around the repaired components.
