Made from billet steel material that is furnace brazed together. The 90 degree end gives the fuel line a much tighter cleaner fit on the injector.
The line nut is -3 and has a 7/16" wrench hex. The hose barb has four barbs that once you slide the hose and crimp a ferrule on it the hose will be good for high pressure fuel systems that run over 250 pounds of line pressure.
