This unique brass petcock fits directly to a 22mm bung on your gas tank, keeping your gas tank looking very clean. It features a 5/16″ diameter hose barb on one end and a fuel filter on the other. Rotating the cylindrical piece with the two grooves is how the fuel is toggled on and off. The fuel line will not and does not rotate while toggling the fuel on/off. No reserve. Made in the USA.
