DESCRIPTION

The fuel pressure solenoid is attached to the rear of the left fuel rail. The solenoid controls and maintains the rail pressure constant along with a control current transmitted by the engine control module (ECM) .

The fuel pressure solenoid is attached to the front of the left-bank fuel rail. The fuel solenoid has a hex nut design with a threaded fitting for mounting the valve to the fuel rail. A lipped-edge metal disk is used to seal the solenoid to the fuel rail. An O-ring seals the fuel return side. The seal is not serviceable and its sealing properties will be lost upon removal of the fuel pressure solenoid. Therefore, the fuel pressure solenoid must always be replaced with the fuel rail as an assembly.

WARNING: The fuel pressure solenoid and left fuel rail are serviced as an assembly.
