A fuel pump module for a fuel tank in a vehicle includes a reservoir adapted to be disposed in the fuel tank and a partition disposed in the reservoir to divide the reservoir into a fuel sensing chamber and a fuel storage chamber. The fuel pump module also includes a conduit conducting return fuel from an engine of the vehicle to the fuel storage chamber of the reservoir. The fuel pump module includes a fuel pump disposed in the reservoir and having an inlet disposed in the fuel sensing chamber and an outlet disposed in the fuel storage chamber. The fuel pump module further includes a fuel usage priority valve to allow fuel from the fuel storage chamber to flow to the fuel sensing chamber to provide the inlet of the fuel pump with fuel from the fuel storage chamber.
