Abstract: Systems and methods are provided for delivering, and controlling the delivery of, one or more fuel additives to one or more fuel hoses at a fuel dispenser. The system comprises a plurality of additive storage tanks, each containing a fuel additive, and a plurality of additive lines for delivering a different fuel additives to the fuel dispenser; a pump coupled for drawing a corresponding additive into and pressurizing the additive line, and a pressure transducer coupled for measuring a pressure generated within the additive line. The plurality of additive lines terminate into one or more output manifolds arranged at the fuel dispenser, wherein each output manifold comprises a plurality of solenoid valves, each coupled to a different additive line. An additive delivery controller is included within the system and coupled to each pump, pressure transducer and solenoid for controlling the delivery of the fuel additives to the fuel hoses.
