A system for supplying fuel to a plurality of fuel injectors of a gas turbine engine is disclosed having first and second fuel distributors and a fuel transfer device which enables fuel to flow from the fuel source to the first and second fuel distributors as a function of the fuel flow rate. The fuel transfer device enables fuel to flow through the first fuel distributor under low fuel flow conditions. The first fuel distributor sequentially supplies fuel to each of a plurality of groups of fuel injectors when the fuel flow rate is below a predetermined threshold value. When the fuel flow exceeds a high threshold value, the fuel transfer device enables fuel to flow through the second fuel distributor which supplies fuel to all of the fuel injectors of the engine.
