Or you can do what hundreds of folks do! Just refill the tank before it gets anywhere near empty. Even with the world's worst reg, end of tank dump will only occur at or near the end of tank. Cheap and easy might be to keep a second tank of gas on hand. When the needle begins to go down, swap the tank. The meter won't show any change until all the liquid is used from the tank, so when it starts to move, you got a day of so to notice.
