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.

[ What is claimed is:] [1.]1. A fuel additive system used in conjunction with a fuel delivery system for an engine comprising:a fuel delivery system having a fuel input conduit in fluid communication with a fuel holding tank,said holding tank being adapted to supply fuel to an engine,a fuel additive tank having an additive conduit joined to the fuel input conduit to provide for fluid communication with the fuel holding tank,said additive conduit having an opened end terminating within the fuel input conduit,fluid pressure reduction means within said fuel input conduit to reduce the amount of fluid pressure on the additive at the opened end of the additive conduit to allow for additive in the fuel additive tank to move towards the fuel input conduit and fuel holding tank,said fluid pressure reduction means consisting of a reduced sized opening volume between two larger sized openings, said fluid pressure reduction means being positioned in the flow path of the fuel deposited in the fuel input conduit before the fuel is deposited in the fuel holding tank,an additive meter in fluid communication with said additive conduit and interposed between the fuel input conduit and the fuel additive tank for metering the amount of additive being supplied to a volume of fuel deposited in the holding tank, andsaid additive meter including a valve normally biased to a closed position by a biasing member to prevent the flow of additive to the fuel input conduit,said valve being responsive to suction action based on the fluid pressure at the fluid reduction means to open and remain opened when the static fluid pressure at the reduced sized opening volume is below a level, said valve being closed by the biasing member when the static fluid pressure increases above this level.
