A distributor type fuel injection pump includes an injection pump to which fuel is supplied from one end of a bore accommodating a slidable shuttle. The shuttle is moved towards the one end of the bore during the filling strokes of the injection pump by way of a first valve means and is allowed to move away from said one end of the bore during an interval between the filling strokes of the injection pump by fuel under pressure derived from the outlet of a feed pump by way of a second valve means. An electrically operable valve is provided to limit the amount of fuel which can flow from said other end of the bore and a sensor is provided to detect the position of the shuttle within the bore and which by way of a control circuit actuates said electrically operable valve. A third valve means is provided to admit fluid under pressure to said other end of the bore when it is required to fill the injection pump.
