A refueling coupling regulator assembly including a housing forming a fluid path. A first stage pressure regulator may be provided within the housing, and may be operable between an un-modulated position and a modulated position to regulate a flow of fluid through the housing. A second stage pressure regulator may be provided within the housing, and may be operable between an un-modulated position and a modulated position to regulate a flow of fluid through the housing. The first stage pressure regulator and the second stage pressure regulator may be operable independent of one another.
