Abstract
The subject matter of this specification can be embodied in, among other things, a fuel pressure regulator system for regulating pressure through a fuel delivery path that includes a fuel pressure regulator valve in the fuel delivery path operable to selectively provide a restriction in the fuel delivery path in response to a reference fluid pressure, a reference fluid path comprising a first orifice, a second orifice and an outlet downstream of the first orifice, the reference fluid path coupled to the fuel pressure regulator valve intermediate the first and second orifices to supply the reference fluid pressure to the fuel pressure regulator valve, and a reference fluid valve upstream of the first orifice operable to selectively provide a restriction into the reference fluid path.
