ABSTRACT:
A fuel delivery system for delivering fuel from a fuel tank to an engine includes a reservoir disposed within the fuel tank and a fuel pump, such as an electrically driven fuel pump, operable to draw fuel from within the reservoir. The fuel pump has a first port and a second port that independently discharge the fuel from the fuel pump. A first jet pump is operable to draw the fuel within the fuel tank into the reservoir. A first flow path communicates between the first port and the engine. A second flow path communicates between the second port and the first jet pump, so that the fuel within the fuel tank is transferred into the reservoir due to the flow of the fuel supplied to the first jet pump via the second flow path.
