This unique brass petcock fits directly to a 3/8″ NPT 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.

Be sure to check out the full line of Prism Supply petcocks for other sizes and finishes.

NOTE: Many custom and aftermarket gas tanks use a 1/4 inch NPT or 3/8 NPT petcock. NPT stands for National Pipe Thread and it is a tapered thread that seals as you tighten the petcock into the threaded fitting on your gas tank.
