This compact petcock threads directly into a 1/4" NPT bung on your gas tank for a clean, simple fuel outlet setup. It features a 5/16" hose barb for standard fuel line and an integrated fuel filter on the tank side of the petcock. Fuel flow is controlled by rotating the grooved cylindrical section of the petcock to turn the fuel on or off. The hose barb remains stationary during operation, so the fuel line does not twist or rotate when shutting the fuel on or off.
