Where does this intake hose go?

[Laneman]

20 hp Briggs, Craftsman LT2000 has a small barbed fitting on air intake under the air filter. Where does other end of hose hook up?

EPA fitting that either goes to the purge valve on top of the fuel tank or to the carbon canister if so equipment on the equipment. if before 2012 then put a rubber plug over it.

Thank you ILENGINE, will look for a fitting on top of the tank, don't think I saw a carbon canister.
