Actually the tube coming from the air cleaner to the carb is metal with two connecting hoses, one at each end. The 8N has the same type of setup. I don"t know if it"ll work, but I"ve looked at my 8N and my 202 and they look similar. This site sells the tube and the connecting hoses. You could get a rough measurement, go to a parts store and get a flexible 1 1/2" top or lower radiator hose that would probably work too.
