Abstract : An apparatus for withdrawing fluid from the fuel tank of an aircraft or missile. A structure of coaxial cylinders with one slidable member responding to transient variations in the direction of the gravitation ('g') force acting on the reservoir by reversing the fluid withdrawal location. When the 'g' force is positive, the fluid is drawn from the reservoir below. If the 'g' force becomes negative, the slidable cylinder translates to align a different set of passage ports within the structure, changing the location of the fluid draw to one within the fluid.
