ABSTRACT:
A multiple fluid feed system for, for example, a turbine engine, comprises a fuel tank, a fuel pump, and means for switching fuel flow from said pump between a return to tank condition and an engine supply condition. A starting fuel reservoir has a cylinder with a fuel inlet and a fuel outlet. A piston in the cylinder is movable from a start position to a run condition in response to movement of the switching means from the return to tank condition to the engine supply condition. A supply of starting fuel is disposed in the reservoir and is biased out of the reservoir upon initial movement of the piston.
