Claims

[Scope of Claim for Utility Model Registration] In a pump control device for a liquid fuel supply device that controls the operation of a liquid suction pump based on a detection signal from a liquid level sensor installed in a storage tank, the pump starts operating. 1. A pump control device for a liquid fuel supply device, comprising: a pump stop means for stopping the operation of the pump when a liquid level sensor does not send out a detection signal of a rise in the liquid level even after a predetermined period of time has elapsed since the liquid level sensor has elapsed.
