FWIW, those using fuel dots and Jersey Modelers might check the diameter of the fuel dot and the fueling barb. The BVM fuel dot in my Bobcat was about .015 to .020 inches less than the diameter of the fueling barb on my Jersey Modeler. Can cause a problem on a cold day when the fill line is less flexible. I have replaced the fueling barb with a short piece of 4mm tubing.
