Abstract
A fuel pump module comprising a fuel pump, a pressure regulator, a supply line check valve, a relief valve, and a flange adapted to engage a fuel supply line that fluidly links the fuel pump module with an injector rail. The pressure regulator is adapted to maintain a predetermined fuel pressure between the fuel pump and the supply line check valve. The supply line check valve is adapted to facilitate a minimum fuel pressure in the fuel supply line. The relief valve is adapted to limit the maximum fuel pressure in the fuel supply line. The supply line check valve, the relief valve, and the flange are integrated to form a single fluidly interconnected structure disposed within a fluid path between the pressure regulator and the fuel supply line. An integrated casing may house the fuel pump and the pressure regulator.
