3. Disconnect the vacuum hose.
4. Disconnect the circlip and remove the fuel pressure
regulator.
5. Apply the oil to O-ring lightly and then replace it.
6. Installation should follow the removal procedure in the
reverse order.
7. Check for fuel pressure and internal leaks by operating the
engine. 2. Discharge the pressure in fuel supply system by pressing
the service valve.
Removal & Installation Procedure
1. Remove the fuel pressure test connector.
