Summary:PURPOSE:To enhance reliability at the time of eventual breakdown in a fuel supply control device, in which an actuator for driving a control rack of a fuel injection pump is operated by a working fluid under control of an electronic controller, by furnishing a means to move the above-mentioned rack manually. CONSTITUTION:Discharge amount of a fuel injection pump 2 is controlled by displacing a control rack 8 axially using an actuator 9. This actuator 9 makes selective control of opening and closing solenoid operated valves 10, 11 by the use of a micro-computer 14 to feed and exhaust air to/from a diaphragm chamber. Thus the direction of driving is controlled. Here a projecting piece 32 is mounted on a rod 22 which is formed as in a single piece with the control rack 8, and one end of the operational lever 30 is put in contact with this projecting piece 32. The other end of this operational lever 30 is coupled with a control lever 35 at the driver seat through a wire cable 34, to provide possibility of control rack's moving in the direction of increase by maneuvering this control lever 35.
