- Use a socket set to remove any clamps or brackets securing the fuel lines.
- Inspect for leaks; replace any damaged sections of the fuel line with new hoses that meet OEM specifications.
- Reattach the fuel lines and secure them with clamps.

3. Replace Faulty Fuel Injectors

Sub-steps:
- Remove the engine cover if applicable to access the fuel rail.
- Disconnect the fuel rail from the intake manifold and detach the electrical connectors from the fuel injectors.
- Carefully remove the fuel injectors from the fuel rail. Replace them with new injectors, ensuring that O-rings are properly lubricated with engine oil before installation.
- Reassemble the fuel rail and reconnect electrical connectors.

4. Replace Fuel Pressure Regulator

Sub-steps:
- Locate the fuel pressure regulator on or near the fuel rail.
- Disconnect the vacuum line and electrical connector from the regulator.
- Remove the regulator by unscrewing it from the fuel rail.
