Am I missing something here?

I know I have the one next to it is the oil tank vent to the air box but it looks like there should be a second hose connected beneath it.

Part numbers would be helpful if I do need something so I know what to ask for when I order it .

Oh yeah I am installing this 83 engine in my 81 if that helps.

Thanks!
