1. A method for assembling a turbomachine fuel injector system, comprising:
attaching a support structure of an air distributor to a casing such that the air distributer is mounted to and contained within the casing and to provide air to mix with a fuel from one or more fuel distribution systems;
inserting and indirectly mounting a fuel manifold into the casing such that at least a portion of the fuel manifold extends through the casing but is sealed to the casing such that the fuel manifold is contained within the casing but is independent such that the fuel manifold does not touch or directly mount to either an interior of the casing or the air distributor within the casing to prevent or reduce thermal transfer from the air distributor to the fuel manifold, and such that the fuel manifold is partially within the support structure;
attaching the fuel manifold to an adapter plate external of the casing;
attaching the adapter plate to the casing; and
attaching one or more air inlets to the support structure to complete the air distributor within the casing such that the air distributor encages a portion of the fuel manifold, wherein the fuel manifold includes one or more fuel distribution systems configured to effuse fuel;
attaching each of the one or more fuel distribution systems to at least one branch of the fuel of the fuel manifold that extends from a base portion of the fuel manifold such that the at least one branch of the fuel manifold extending from the base portion and not encaged by the air distributor extends through a first opening in the air distributor, traverses an axial distance, and then extends back through a second opening of the air distributor; and
connecting the at least one branch of the fuel manifold to a respective fuel distribution system of the fuel manifold.
