ABSTRACT:
A fuel system for a diesel engine may have a fuel tank, a fuel pump, a fuel filter module, and a fuel rail. The fuel filter module has a vacuum side and a pressure side. The vacuum side is connected to the fuel tank and to the inlet side of the fuel pump. The pressure side is connected to the outlet side of the fuel pump and to the fuel rail. The fuel filter module has a pressure regulator and a filter element in the pressure side. The pressure regulator is disposed between the outlet side of the fuel pump and the filter element. The pressure regulator recirculates unfiltered fuel to the vacuum side of the fuel filter module.
