Abstract
A liquid fuel injection pumping apparatus for supplying fuel to an engine includes an injection pump to which fuel is supplied through a feed passage in a distributor member from a low pressure pump. Fuel is delivered by the injection pump through a separate delivery passage which can register with an outlet. In order to enable air to be purged from the passages and injection pump, the delivery passage during the time fuel is being supplied to the injection pump is arranged to register with a further port which communicates in the example with a fuel supply tank. A restrictor is provided to control fuel flow through the further port.
