cc1979

I've started a couple threads around getting my 1979 928 running again and it's coming along. On the cap to the air filter housing on the bottom of the passenger side of the cap, I see a port for something to hook up to it. I don't see anything in my engine bay hanging around that would go to it. What is supposed to go there? Thanks!

On my '81 there is an air hose from diverter valve for smog that goes there. It is tied into the charcoal canister I believe.
