Abstract
Method and apparatus for adjustable fuel pressure module. In accordance with an embodiment of the present invention, an apparatus for regulating fuel pressure comprises a body configured to mate to a fuel filter housing, a spring seat assembly configured to seal an opening in the fuel filter housing according to a force applied by a pressure regulating spring acting on the spring seat assembly, and a pressure regulating spring adjusting assembly mounted to the body, configured to constrain an adjustable length of the pressure regulating spring, wherein the spring is constrained between the spring seat assembly and the pressure regulating spring adjusting assembly. A force exerted upon the spring seat assembly by the pressure regulating spring corresponds to a desirable fuel pressure. The spring seat assembly is configured to unseal the opening in the fuel filter housing responsive to a fuel pressure greater than the desirable fuel pressure.
