Abstract
A fuel pumping apparatus comprises a body defining a first bore within which a pumping plunger is reciprocable. The first bore communicates with a spill valve. A pilot piston is moveable within a pilot bore under the influence of the pressure within the first bore. A piston member is slidable within a blind drilling provided in the pilot piston such that upon movement of the pilot piston, fuel within the drilling is pressurised to a higher pressure than fuel within the first bore. Passage means connects the drilling with a fuel injection nozzle.
