I am trying to find a source for the short, black, rubber hose that connects the cam cover vent to the air cleaner on carburated e3/e9's. My old one is ~ 20mm id x 127 mm long (~ 5" long). Neither the Wallothnesch nor Maximillan sites seem to show it, leading me to believe that everyone just uses generic 20 mm hose. I tried searching McMaster-Carr, but found few options in metric-sized hose as large as 20 mm id. At present, I'm using a piece of clear, 3/4" id hose from ACE Hardware and it sort of works, but is a very tight fit, making air cleaner installation difficult.
Expected to find it on this diagram, but no luck.
