A fuel supply or management system in which fuel is delivered in pulses for each power stroke of the engine with the quantity of fuel in each pulse being determined by the speed and load of the engine through a pump control modifying the effect of operation of a reciprocating variable volume, positive displacement fuel pump by controlling the effective stroke of the pump. Fuel is delivered in accordance with the speed of and the load on the engine so that only the amount of fuel required is delivered thereby minimizing the exhaust of unburned fuel and pollution of the environment and eliminating the need for a fuel return line for excess fuel supplied.
