HOSE, Air silencer to manifold 4-1/2" long. For service use 203909 cut to length

Someone took off the silencer and failed to replace hose. It wouldn't be there if it wasn't needed.

There normally will be a bit of fuel mist blow back out of the carburetors at various speeds. That would make a mess. So, the hose is provided to suck that fuel into the intake manifold, where it goes through with the rest of the fuel to be burned.
