| -2- in which a sylphon metal diaphragm was used. Apparently the cloth was found at least equal to the metal concertina in actual use. The King Seeley Corporation points out that with a feed of this type, it is not necessary to provide an air vent in the filler cap when their gauge is used, as the small vent in the King Seeley gauge is ample for a continuous fuel feed of this type.
