Abstract
A fuel system for supplying fuel to a pair of injection nozzles of an engine comprises a pair of pumps which can only deliver half the maximum amount of fuel which may be required. Each pump supplies fuel to a respective nozzle when the fuel required is less than half and the system includes a pair of valves which are operated to allow both pumps to deliver fuel through one nozzle when more than half the maximum amount of fuel is required, the pumps then being operated at twice the previous rate to supply fuel to the nozzles in turn.
