Abstract: Fuel injecting apparatus and methods are disclosed having components configured to provide a desired radial orientation of nozzle spray holes. Alignment rings for coupling fuel injector components include a ring body that includes a plurality of alignment guides configured to be received by complementary alignment features in the fuel injector components so as to align the fuel injector components in a desired orientation relative to each other. The plurality of alignment guides includes a primary alignment guide and at least one secondary alignment guide that is different from the primary alignment guide and each alignment guide in the plurality of alignment guides is equally spaced apart about the inner sidewall surface.
