Found this in digging around through some of my dad's stuff. Vacuum gauge?

Starting to do some more real detective work here on the vacuum lines. Took a picture of the vacuum hose diagram mounted on the underside of the hood so I would have something to refer to. Removed air filter housing to get a clearer view of carb and connecting hoses. At back of carb there 2 hoses that meet at a 3-way tee. One hose comes from the back side of the carb down low on the housing. Another hose comes from a diaphragm mounted up higher on the side of the carb. They meet together and a single hose leading away goes nowhere! It's loose! See pictures. Not sure where the loose end goes, so I took a picture of a couple of small boxes (?) mounted on firewall. In the picture you can see a fitting on the top being unused (it has been like that since I bought car and noticed nothing attached to it). Today I did notice an unused fitting on the bottom of one of these boxes (not sure what to call them). It's there in the picture if you look hard enough.
Should that loose hose connect to one of these fittings? Or should I keep looking for something else?

In my opinion, there are two different kind of vacuum hoses. New (or good) or wore out/bad (ie: broken, swollen or hard as a rock) hoses.Dorman vacuum hoses okay?
These pictures are from my '77 318. The later BBD's and Holley 2280/6280 used a "T" on this hose and earlier BBD's (like my '77) used a different carburetor port.At back of carb there 2 hoses that meet at a 3-way tee.

Yes, that's a vacuum gauge. If you hook it up, just be sure to use a manifold vacuum source and not ported. Any nipple on the vacuum "tree" behind the carb will be manifold vacuum.Found this in digging around through some of my dad's stuff. Vacuum gauge?
