Abstract: A process includes manufacturing a gas turbine fuel injector body having a stub flange extending radially outward about a circumference of the gas turbine fuel injector body. The stub flange is sized to engage a stepped ledge along a central opening of a mounting flange. The central opening is sized to receive the gas turbine fuel injector body. A gas turbine fuel injector includes a gas turbine fuel injector body and a mounting flange. A method of mounting a gas turbine fuel injector includes placing a stub flange of a gas turbine fuel injector body between a surface of an injector boss and a stepped ledge of a mounting flange. The method also includes securing the gas turbine fuel injector to the injector boss with a plurality of bolts, each bolt extending through a mounting hole in the mounting flange and into a threaded hole in the injector boss.
