1. Use a wrench to disconnect the fuel line fittings.
2. Remove the old line and replace it with a new one.
3. Reconnect the fuel line fittings securely.

3. Inspect and Replace Fuel Injectors

Tools Required: Injector puller, torque wrench
Disconnect the electrical connectors from the fuel injectors.
Remove the fuel rail by unscrewing the mounting bolts.
Pull out the fuel injectors; inspect O-rings for damage.
Replace any faulty injectors and O-rings.
Reinstall the fuel rail, ensuring injectors seat properly.
Torque the bolts to the manufacturer's specifications.

4. Check and Repair EVAP System

Inspect the EVAP canister and associated hoses for damage.
Replace any cracked hoses or faulty components.
Ensure the purge valve and vent valve operate correctly.
If necessary, replace the EVAP canister.

5. Pressure Test the Fuel System

Tools Required: Fuel pressure gauge
Connect the fuel pressure gauge to the fuel rail.
Start the engine and monitor the fuel pressure.
If pressure is below specifications, check for leaks or faulty fuel pump.
