Solution

1. Preparation

Gather tools and parts for the repair.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool if the engine has been running.

2. Repairing Fuel Lines

Tools Required: Socket set, screwdrivers, fuel line disconnect tool, rags
Locate the damaged section of the fuel line.
If necessary, relieve the fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Use the fuel line disconnect tool to remove the damaged section.
Install the new fuel line and secure it with the appropriate clamps.
Reconnect the fuel pump fuse and the negative battery terminal.

3. Replacing Fuel Injectors (if necessary)

Tools Required: Socket set, torque wrench, injector puller
Remove the engine cover (if equipped) to access the fuel rail.
Disconnect the electrical connectors from the fuel injectors.
Unscrew the fuel rail bolts and carefully lift the fuel rail with the injectors attached.
Remove the old injectors from the fuel rail and replace them with new ones.
Reassemble the fuel rail and reconnect all electrical connectors.

4. Checking the EVAP System

Tools Required: Vacuum pump, smoke machine (if available)
Inspect all hoses connected to the EVAP system for cracks or disconnections.
If a smoke machine is available, use it to check for leaks in the EVAP system.
Replace any faulty components as needed.
