Hi all:

First time changing my air filter.  As I took the element out the cleaner, the base fell off the carb and I noticed the hole in the bottom.  What does it do?  Should there be something attached to it?  As I looked for an answer I see that I have a hi-po cleaner for 60's-70s Fords.  The shopping site pix show the hole both open and plugged.  I attached my carb setup if that helps.  

Thanks

Tim

I was thinking the PCV used its own filter on the outside of the carb air cleaner.

the other emmission "vent" I thought of was the charcol canister and I think it should be "inside" the carb air filter.   Shop manual doesn't show though.

 

EDIT>>>>

I just visited the CJ Parts site and saw this filter does not have a "body" for beyond the filter element, SO, as Garth first replied, it would be used for PVC

Thanks for the replies!   I need to get closer and see if it's connected via a PCV valve ('regulator valve' on the diagram), but the hose (highlighted yellow) that comes out of my driver's side valve cover goes back into the manifold.  

It sounds like a more stock setup would be to have that hose go to the air cleaner, then have a hose from the lower port on the carb connected to the oil filler cap.

With all of that said the car seems to run well and I haven't detected any oil leakage.
