2. Use the fuel line disconnect tool to carefully detach the lines.
3. Inspect the lines for any signs of wear, cracking, or leaks.
4. Replace any damaged fuel lines with OEM parts.
5. Reconnect the fuel lines and ensure they are secure.

3. Check and Replace Fuel Injectors

Tools Required: Socket set, torque wrench, fuel injector removal tool.
Sub-steps:
1. Remove the engine cover (if applicable) to access the fuel rail and injectors.
2. Disconnect the electrical connectors from the fuel injectors.
3. Unbolt and remove the fuel rail to access the injectors.
4. Inspect the injectors for leaks; replace any faulty injectors with new ones.

Sub-steps:
1. Remove the existing fuel cap and inspect the rubber gasket for damage or wear.
2. Replace the fuel cap with a new OEM cap if the gasket is damaged or if the cap doesn’t seal properly.

5. Test Fuel Pressure Regulator

Tools Required: Fuel pressure gauge.
Sub-steps:
1. Locate the fuel pressure regulator on the fuel rail.
2. Attach the fuel pressure gauge to the test port on the fuel rail.
3. Turn the ignition key to the "On" position (do not start the engine) and check the pressure reading.
4. If the pressure is outside the specified range, replace the fuel pressure regulator.
