Where does this vacuum tube go? Smog Pump 1994 5.8

Hey guys with a 351/302 with similar smog equipment!

There's some kind of hose hookup that goes out the bottom of this pump. Can you check your truck and see where the dang thing routes to?

Okay... it's called the TAB valve.

Solved it. There's an attachment on the small vacuum tube assembly that comes around the back of the intake plenum. It has a rubber hose that attaches to the plastic assembly.

Does it run towards the Firewall and then behind the block?

Nope... wrong type of tube. I have a few of those in my living room but certainly none in the truck!
