Dennis,

I looked tonight at my air filter, there is a line coming from the top of the round filter that has been capped off. Isn't this suppose to connect to the charcoal filter? Where is that suppose to go? I assume I should connect that properly correct? I think a VW mechanic I used in Long Beach NY put a ball bearing in it and capped it off.
