Abstract
A method and system for determining the level of fuel contained in the tank of a motor vehicle includes a fuel pump disposed in the tank for creating a flow of fuel in the tank. An elongated tube is placed vertically in the tank. The system also includes a venturi tube coupled between the fuel pump and the elongated tube for creating a vacuum as a result of a portion of the flow of fuel therethrough from the fuel pump thereby drawing fuel vapor from the elongated tube at a varying pressure, the pressure decreasing as the amount of fuel vapor in the tank increases. A controller is coupled to the elongated tube for determining the level of fuel in the tank based on the pressure.
