Abstract
One or more techniques and/or systems are disclosed for providing for improved liquid fuel delivery, by helping to mitigate damage to pumps when operated in an undesired condition. A sensor detects the presence of a liquid fuel at the inlet to the pump during pump operation, and sends the signal to a controller. Based on the detection signal from the sensor, the controller can determine whether a desired amount of liquid is present at the inlet to the pump. If a desired amount of liquid is not identified at the inlet to the pump, the controller may interrupt the power provided by a power supply, which is supplying power to operate the pump, thereby interrupting operation of the pump.
