ABSTRACT:
Several embodiments of induction systems having forced induction and a regulated fuel pump for delivering fuel to the charge forming device at a pressure that is related to the pressure in the induction system. In some embodiments the pressure is sensed above the level of the fuel in the fuel bowl of the charge forming device, and in others the pressure is sensed in a plenum chamber upstream of the charge forming device inlet. A check valve arrangement is also provided in the fuel line in one embodiment for preventing the backflow of fuel under conditions when the engine is stopped.
