ABSTRACT:
An automotive fuel system including a reservoir having upper and lower chambers on opposite sides of a partition in the reservoir, a high pressure fuel pump having an inlet connected to the lower chamber, a low pressure fuel overage return pipe returning overage fuel directly to the lower chamber, and a low pressure pump transferring fuel from the tank directly to the upper chamber. A drain in the partition conducts gravity induced fuel flow from the upper chamber to the lower chamber at a rate equal to the difference between the rate at which the high pressure pump withdraws fuel from the lower chamber and the rate at which overage is returned to the lower chamber through the overage return pipe.
