A liquid fuel and additive mixing apparatus for accurately proportioning the liquid additive into the liquid fuel for a vehicle such as a truck tractor includes a control unit preferably located in the cab of the truck tractor and connected to the vehicle electrical system for supplying electrical power thereto. A pump unit mounted to the truck tractor has an additive reservoir, pump, and valve controlled pressure delivery connections with the fuel tank and electrical connections with the control unit. When a known quantity of fuel is put into the truck tractor fuel tanks, the quantity is entered in the control unit and the control unit is activated to energize the pumps and open the valves for delivery to the fuel tanks of the predetermined quantity ratio of additive to the quantity of fuel put in the fuel tank. The pump is a constant output pressure pump and a nozzle orifice in the delivery connections between the valves and the fuel tanks is of a size that with a predetermined pressure, the orifice will deliver a certain quantity of additive each minute to the respective tanks for accurate proportioning of the additive and fuel therein.
