Tools Required: Wrench set, screwdrivers, safety glasses, gloves.
Carefully inspect fuel lines for visible damage or leaks.
If a leak is found, use a wrench to carefully loosen and remove the affected fuel line.
Catch any remaining fuel in a container for safe disposal.

3. Replace Damaged Components

If a damaged section of the fuel line or fuel injector is found:
- Obtain the correct replacement parts (fuel line, injector, O-rings).
- Install the new fuel line or injector, ensuring that all connections are tight and secure.
- Use new O-rings for injectors to ensure a proper seal.

4. Reconnect Fuel System

Reconnect any removed fuel lines and ensure all clamps are secure.
Reconnect the negative battery terminal.
Turn the ignition to the "on" position (without starting) to prime the fuel system and check for leaks.

5. Final Check

Start the engine and let it idle.
Visually inspect the fuel lines and injectors for any signs of leaks.
If no leaks are evident, proceed to test drive the vehicle to ensure proper operation.
