A fuel system [100] for a diesel engine [102] may have a fuel tank [106], a fuel pump [110], a fuel filter module [108], and a fuel rail [112]. The fuel filter module [108] has a vacuum side [118] and a pressure side [120]. The vacuum side [118] is connected to the fuel tank [106] and to the inlet side [122] of the fuel pump [110]. The pressure side [120] is connected to the outlet side [124] of the fuel pump [110] and to the fuel rail [112]. The fuel filter module [108] has a pressure regulator [138] and a filter element [140] in the pressure side [120]. The pressure regulator [138] is disposed between the outlet side [124]of the fuel pump [110] and the filter element [140]. The pressure regulator [138] recirculates unfiltered fuel to the vacuum side [118] of the fuel filter module [108]. |
