ABSTRACT:
A fuel pumping apparatus for supplying fuel to an internal combustion engine includes an injection pump which delivers fuel through a delivery passage which includes a spring loaded delivery valve. A vent conduit extends from the delivery passage, and communicates with a vent conduit during a delivery stroke of the injection pump. The vent conduit communicates with the delivery passage intermediate the injection pump and the delivery valve, and the vent passage includes a screwed plug at its end and a valve element which is resiliently loaded into contact with a seating. The seating is positioned adjacent the vent conduit so that the amount of fuel in the conduit during normal operation of the apparatus, is as small as possible.
