*91f150*

So I just noticed last night there is a long plastic hose running out of the valve cover (where it breaths) and is just kind of sitting against the firewallat the other end, is this normal? If not how is it supposed to be hooked up?
It's a 1991 F150 302

Should be connected to the air box that how my old 302 was and it was a 88
