ABSTRACT:
The present invention refers to a fuel pressure regulator assembly and method for regulating the pressure of the fuel supplied to the fuel rail at a predetermined pressure. The fuel pressure regulator includes a housing and fuel cover for containing the fuel pressure regulator and submersing the fuel pressure regulator in fuel at all times. A valve element allows excess fuel to exit the fuel pressure regulator and return to the fuel tank for reuse. The fuel component assembly also allows for a method of reducing turbulent fuel flow and for controlling noise and hydrocarbon emissions. The method is achieved by providing a containment assembly that submerges the pressure regulator in fuel for containing and directing fuel flow path.
