Hey Grant, does the hose connect to a device that has a cylinder looking thing on it? If so, you are dealing with one of the small hoses that the governor uses. As BK alludes to below the main air supply hose from the compressor is braided steel and very large and generally goes about 2-3 feet before it connects to the bus at the ping tank. The small hoses (2) on the governor are used for delivering operating pressures of the coach air supply to the governor and are not designed to carry high volumes of air.
