ABSTRACT:
A fuel pumping apparatus includes a high pressure pump and a low pressure pump which supplies fuel thereto. A further low pressure pump supplies fuel at a pressure which is modified to provide a control pressure which is used to control the delivery quantity of the pump. The pump draws fuel from the lower portion of a reservoir and the pump from the upper portion whereby in the event of fuel starvation the high pressure pump will be starved of fuel before the control pressure is lost.
