Identify This Part Please!

Hey believe this or not. Another mechanic who is in business called my buddy an inmport mechanic (hey he drives a 62 Desota) Anyway this other guy calls my buddy to ask about the "electric turbo" on this VW. So being confused and wanting to see an electric turbo went to his garage to see....an emissions air pump! And this guy has an inspection station! I remember not knowing anything. I know it was just yesterday but we all start somewhere. Stick with FABO Vanleer...these guys help me all the time!
