Abstract
A fuel pump designed to prevent vapor lock. The pump comprises an inlet check valve located between a pumping chamber and a reservoir. The inlet check valve allows the flow of fluid from the reservoir into the pumping chamber. The inlet check valve is constructed such that when a combination of both liquid and vapor is present in the pumping chamber, the liquid and vapor is allowed to flow from the pumping chamber back into the reservoir; but when the pumping chamber is filled only with liquid, the inlet check valve prohibits flow from the pumping chamber into the reservoir.
