Solenoid, Fuel Pressure: Description
NOTE:
The fuel pressure solenoid is not a serviceable item.
The fuel pressure solenoid (2) is attached to the rear of the fuel rail (1). The tip of the fuel pressure solenoid (2) uses a knife edge, for metal to metal sealing. The knife edge actually deforms the metal in the fuel rail in order to seal the surfaces. The solenoid must be replaced when ever it is removed from the rail. The solenoid controls and maintains constant rail pressure with a control current transmitted by the Powertrain Control Module (PCM).
