This is the best fuel method I have found. The "Kwik Fill" fueling valve by Dubro. Part#334. It just splices into the fuel supply line. When you insert the supplied fuel niple it automatically shuts off the flow to the carb. Pretty slick. They sell a mounting bracket to mount to the firewall (wood) but its just as simple to use a piece of aluminum angle. You can also mount it right on the fuse. Joe
