76 Dart Sport Vacuum Hoses

[SDHomesteade]

Need a bit of help here fella's. Got New Vacuum Lines for the 76 Dart Sport with the /6 in it and there is one line that is missing completely and don't see it on the hose diagram on the fender. I have Thingy (for lack of a better word right now) on my carb that comes out the side of it and screws on, It looks as if it had a hose on it at one point in time (see picture with white arrow pointing to thingamajig) but it's NO WHERE on the Diagram on the Fender. The Diagram also shows a Vacuum Reservoir and Amplifier that are NOT on this car, nowhere. Where does this Thingamajig hook up to??
I've also attached a pic of the vacuum diagram that is on the fender.

I've never had any of that factory nonsense still be functional by the time a 40 yr old car makes it's way to us.

It should just be a filtered one way check valve. Hook a hose too it and see if you can push air or pull a vacuum.
