I would concentrate on a good shut off valve. The metal-to-metal needle and seat simply cannot be trusted to hold back fuel indefinetly. Like Dave said, take one of your shut-off valves apart and see if there is corrosion, gunk or debris that you could clean up or lap out. And I, too, always empty the tank when not being used. That way, it can’t leak out in my basement and blow the house up, not to mention forming gunk. I am with you, that the shut off valve SHOULD work, though. The needle and seat just won’t. Not over night.

Long live American manufacturing!
