A fuel pump uses an expanding spring to pressurize liquid fuel and cause it to flow through a pump outlet port. A cam and cam follower cause a piston to move in a direction opposite to the pumping stroke in order to transfer fluid from a first chamber to a second chamber within the body of the pump. During the spring actuated pumping stroke, liquid fuel is drawn from a fuel reservoir into the first chamber of the pump for later transfer to the second chamber during the return stroke caused by the cam mechanism. A flexible shaft connects the cam to mechanism to a source of motive power to allow the pump to be displaced from the source of motive power and away from certain potential sources of heat.
