A pilot fuel regulating system includes a pilot fuel governor for supplying varying amounts of pilot fuel to an engine. A piston housed within an elongated bore moves longitudinally therein in response to changing engine speeds to regulate the flow of fuel through the governor. A minor diameter portion and chamfer portion of the piston allow the passage of varying amounts of fuel through the bore. In preferred embodiments, the minor diameter portion is elongated to define a moving reservoir within the bore for dampening fuel pressure oscillations.
