Abstract
A fuel pumping apparatus for supplying fuel to a compression ignition engine includes a positively reciprocated plunger which during a pumping stroke displaces fuel from a first pump chamber to an outlet and draws fuel into a second pump chamber. The apparatus includes an inlet chamber from which fuel is supplied to the second pump chamber, and a diaphragm pump which draws fuel into the inlet chamber through a fuel inlet. The pump drive shaft extends through the inlet chamber and carries vortex creating means whereby air entering the inlet chamber will collect around the shaft to cause early starvation of fuel supply to the associated engine in the event substantial quantities of air enter through said inlet.
