73 Charcoal canister to 1406 carb

The crankcase vent IS PART of the PCV system. Without it, the PCV system is not complete. You should have both on a street driven engine.

Ok, I think I get what your talking about now. I was talking about just the line coming off the pcv valve. Yes on the other side I did have a breather with a nipple and a hose running to the air cleaner in my old set up. I had planned on an edelbrock valve cover breather without the nipple since I had no where to run the hose. Your saying I should get the one with the nipple and run the hose to the air cleaner and connect with this 1205 part to complete the system? If I do that then the only way to connect the canister bowl vent line would be to get a second connection? Thanks for all the help, never done any set up like this before and want to get it done right!
