Carb hook up/ Pcv question.

I think what threw me is when I went in AutoZone what I have was called a pcv breather on their packaging. I plugged it with a breather cap though. Thanks man.
The breather is the inlet for the pcv system. For it to be dead correct, it really needs to connect to the air cleaner with a hose. Here is a proper PCV system.
