Abstract:
A vehicle fuel system may employ a fuel pump module with a reservoir within a fuel tank. The system may also employ a fuel injection common rail, a fuel supply line leading from the fuel pump module reservoir to the fuel injection common rail, and a fuel return line leading from the fuel injection common rail through a fuel pump module flange. Additionally, the system may employ a first return fuel check valve to release fuel only into a reservoir jet pump and/or a transfer jet pump, while a second return fuel check valve may release fuel only directly into the fuel pump module reservoir. An electric fuel pump within the reservoir may have a fuel pump check valve and supply fuel only to the reservoir jet pump and/or the transfer jet pump, and not to an engine, when activated by a pressure sensor in the fuel return line.
