Abstract
A fuel system for a vehicle comprising a fuel tank having a fuel tank reservoir. A lift pump is outside of the fuel tank and includes an inlet, and first and second outlets, with the inlet being configured to receive fuel from the fuel tank. The lift pump is configured to output fluid from the first outlet at a first prescribed pressure. A venturi pump is located within the fuel reservoir and defines a venturi pump reservoir. The venturi pump includes a venturi jet including a drive inlet configured to be fluidly connectable to the first outlet of the lift pump to receive fluid therefrom. A suction inlet is configured to be placeable in fluid communication with the fuel tank reservoir and to draw fluid from the fuel tank reservoir into the venturi pump reservoir in response to fluid flowing through the venturi jet at the first prescribed pressure.
