A single, unitary thermal management system (TMS) manifold for a gas turbine engine is provided which comprises one or more interfaces for mounting various thermal management system components directly to the TMS manifold. The TMS manifold also defines fluid passages for transferring fuel, engine lubricant or generator oil from one component to another component. Packing numerous fuel system and lubricating system components within the TMS manifold reduces cost and weight and simplifies maintenance.
