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.
