where does missing tube go to (stupid blowby ?)

sorry for the dumb ? but I looked at all the blowby treads - most said replace the tube/hose (the rear one that comes off the valve cover)...but mine has been missing since I acquired her (93 4.0 w/ 172,000). So, my question is where can/ should I get a new one, & most importanttly, where on the intake does it plug into? (I searched 4.0 pics but couldn't see it)

also, will this solve my blowby problem?

Thanks,
Erik

I'm not sure about the HO's, but Napa carries the hose for the Renix. The other end attaches to the intake manifold near the tb.
