    Patent number: 6321692
    Abstract: A fuel additive delivery system used with the fuel system of an engine. When fuel is added to a holding tank fluid pressure is reduced at a Venturi guide. The Venturi guide is connected to an additive delivery system. When the static fluid pressure in the Venturi guide falls below a level a sucking action is initiated. This action opens a normally closed valve in a meter system connected to an additive tank. When the valve opens additive flows from the additive tank into and past the Venturi guide into a fuel holding tank for the engine.
