A fuel tank assembly includes a fuel tank and a fuel pump module. The module supports a fuel pump that delivers fuel to an engine of a vehicle, and includes a module housing that provides a cavity that receives the fuel pump, a reservoir that is actively filled with excess fuel discharged from a fuel pressure regulator, and a fuel return passageway that directs excess fuel discharged from the pressure regulator to the reservoir. When the fuel tank assembly is inverted, as may occur when the vehicle is operating under certain dynamic conditions, the discharged fuel is retained within the reservoir, and is supplied to the fuel pump inlet via a wicking filter that extends between the reservoir and the fuel pump inlet. As a result, engine stall due to lack of fuel during certain dynamic conditions can be delayed or avoided.
