- Cut the damaged section of the line if necessary and replace it with a new line.
- Secure the new line with the appropriate clips and brackets.

3. Check and Replace Fuel Injectors

Remove Fuel Rail: Disconnect the fuel lines from the fuel rail and remove any electrical connectors.
Replace Injectors: Remove the old fuel injectors from the rail and replace them with new ones. Ensure O-rings are lubricated before installation.
Reinstall Fuel Rail: Reattach the fuel rail, ensuring all connections are secure.

4. Inspect and Replace Fuel Cap

Check Fuel Cap: Inspect the fuel cap for cracks or wear.
Replace If Necessary: If damaged, replace the fuel cap with a new OEM part to ensure a proper seal.

5. Test Fuel System Pressure

Connect Fuel Pressure Gauge: Attach a fuel pressure gauge to the fuel rail.
Start Engine: Turn on the ignition to prime the fuel system and check for proper pressure readings.
Identify Leaks: If pressure is low, inspect for additional leaks in the fuel system.
