Abstract: A precision additive dosing device comprising a liquid additive tank, dosing pump, filter, electric actuator, and pump control unit. Upon completion of fueling, the control unit is input with the corresponding volume of fuel just delivered. The pump starts until a time is reached that achieves the correct blend of additive for the fuel. The dosing pump delivers a constant volume of additive with time being the only variable to achieve the correct ratio of additive to fuel. Operation of the pump may be delayed or the time of pump operation may be increased during low ambient temperatures by the pump control circuit. Additionally, a heater may be used to heat the additive in similarly low temperatures.
