    • PROBLEM TO BE SOLVED: To provide an actuator for a fuel auxiliary supply device in a diesel engine capable of automatically performing fuel supply work with a manual pump and capable of always supplying the fuel in a suitable amount.
      SOLUTION: This actuator is provided with clampers 4a and 4b for clamping and unclamping a device body 1 to the manual pump by a clamping cylinder 3; a pumping cylinder 6 abutting onto a pumping knob of the manual pump so as to perform pumping actuation; and a sequencer 10 which controls clamping and unclamping of the clamper; stops the pumping actuation and controls to unclamp the clampers 4a and 4b when stroke time reaches a predetermined value by detecting the change of the stroke time from a upper end to a lower end of the pumping cylinder 6 with an inner pressure raise of the manual pump due to the suction of the fuel.
