Fuel Pressure Solenoid: Installation

Review the high pressure fuel system warning before beginning repair (Refer to FUEL SYSTEM - WARNING)

WARNING: NO SPARKS, OPEN FLAMES OR SMOKING. RISK OF POISONING FROM INHALING AND SWALLOWING FUEL. RISK OF INJURY TO EYES AND SKIN FROM CONTACT WITH FUEL. POUR FUELS ONLY INTO SUITABLE AND APPROPRIATELY MARKED CONTAINERS. WEAR PROTECTIVE CLOTHING.

CAUTION: There is a special tightening procedure for the fuel rail solenoid that must be followed along with the proper use of a torque wrench. Therefore the fuel rail must be removed before installing the fuel pressure solenoid. Attention must be paid to the sealing ring before assembly. If the sealing ring is damaged when assembling, this could result in a not so visible leak.

NOTE: Observe the alignment of the pressure solenoid. The electrical connection must point in the same direction as the connection of the injection line at the fuel rail.

Screw the fuel pressure solenoid with new sealing disc to the fuel rail until hand tight. See Figure.
Tighten the fuel rail solenoid as follows :
1. Tighten the nut to 60 N.m (44 ft. lbs.)
2. Loosen the nut 90 degrees.
3. Retighten the nut to 80 N.m (59 ft. lbs.).
Install fuel rail (Refer to FUEL SYSTEM/FUEL INJECTION/FUEL INJECTOR - INSTALLATION) .
Connect negative battery cable.
Start engine, allow to warm, turn engine off and inspect for leaks (Refer to FUEL SYSTEM - DIAGNOSIS AND TESTING) .
