In a method of making a combination of a fuel manifold having a fuel receiving chamber therein and a plurality of like fuel control devices mounted to said manifold and having inlet projections extending into said manifold to receive fuel from said chamber thereof, said manifold having a pair of opposed spaced apart substantially flat front and rear walls and a pair of opposed spaced apart substantially flat side walls interconnecting said front and rear walls together, one of said side walls having a plurality of spaced apart openings therethrough and through which said inlet projections of said control devices respectively extend, the improvement comprising the step of forming said side walls to be spaced apart a distance that will permit two of said control devices to have said inlet projections thereof respectively extend through coaxially aligned openings in said side walls so that said two of said control devices can be respectively mounted to said manifold in coaxially aligned relation on opposite sides thereof.
