ABSTRACT:
A liquid fuel pumping apparatus for supplying fuel to an internal combustion engine includes a plunger slidable within a bore to which can be connected an outlet which in use is connected to an injection nozzle. The bore can also be connected to a drain through a spill valve, the spill valve when open allowing fuel to spill from the bore instead of flowing to the outlet. The spill valve includes a valve member which when the spill valve is open closes off the connection between the outlet and the bore.
