The Prism Supply Co petcocks are guaranteed for life! If you're having an issue with it you can send it back to them and they will rebuild it for no additional cost!
This unique petcock fits direct to a 1/8 BSP thread on your gas tank. This keeps your gas tank looking very clean. It features a 5/16" diameter hose barb on one end and a fuel filter on the other. We recommend using our 1/4" Fuel Line for a snug, leak-proof fit. Rotating the cylindrical piece with the two grooves is how the fuel is toggled on and off. The fuel line does not rotate while toggling the fuel on/off. No reserve.
