B21F component question 200 1979

There are 2 hoses...both are S shaped. As Lucid wrote this Aux Air Valve is a bypass system. It bypasses the throttle plate. On my 80 B21 non turbo.

The top hose attaches to the intake manifold just behind the Cold Start injector.
The hose off the bottom of the Aux Air Valve attaches just below the throttle plate at that Thumb Screw valve, but that hose T's off into a Plastic Vacuum Valve , which itself has a small hose that goes to the other nipple on the Thumb Screw Valve.

So that's about as clear as mud....right?

Why oh why don't they make 240s anymore :(
