Replace the damaged fuel lines with new ones, ensuring proper routing and securing with clamps.
Reconnect the fuel lines and tighten securely.

3. Check and Replace Fuel Injectors

Tools Required: Socket set, injector puller tool (if necessary)
Remove the engine cover to access the fuel rail.
Disconnect the electrical connectors from the fuel injectors.
Unscrew the fuel rail bolts and carefully remove the fuel rail with injectors attached.
Inspect the injectors for leaks; replace any faulty injectors with new ones.
Reinstall the fuel rail and ensure all connections are secure.

4. Inspect and Replace the Fuel Pressure Regulator

Tools Required: Socket set, fuel pressure gauge
Locate the fuel pressure regulator, typically mounted on the fuel rail.
Disconnect the vacuum line and electrical connector (if applicable) from the regulator.
Remove the regulator from the fuel rail and inspect for leaks.
Replace with a new fuel pressure regulator if necessary.
Reconnect all components properly.

5. Check the Fuel Tank and Evaporative System

Tools Required: Socket set, fuel tank straps tool
