Fuel Pressure Regulator: Service and Repair

Fuel Pressure Regulator Installation
(1) When connecting the fuel-pressure regulator to the fuel rail, apply a drop of new engine oil to the 0-ring, and then insert, being careful not to damage the 0-ring.

Caution: Be sure not to let engine oil in the fuel rail.

(2) Check to be sure that the fuel pressure regulator turns smoothly. If it does not turn smoothly, the 0-ring may be trapped, remove the fuel pressure regulator and then re-insert it into the fuel rail and check once again.

(3) Tighten the bolts to the specified torque.

Specified tightening torque: 9 Nm (6.5 ft.lbs.)
