Check valve is made from billet brass bar stock, wrench hex is .875", one side is -8 ORB reverse flare and the other side is -8 37 degree flare with the end of the check valve having 7/16-20 threads to install a bypass pill into for fuel volume control if the racer chooses.
Housing is laser etched with flow directions and outer housing has been trimmed to give the check valve a nice stream-lined look and weight savings.
