What is this called and what is it's function?

Mine is cracked all up



sorry I should have used red to draw my box
it's just below the map sensor in the box that I drew
looks like a inline check valve or something
Thanks for the help

check valve that directs vacuum to the heater control vacuum motors (defrost, vent, etc.)

i think the other line attatched to it goes to the cruise control.

cool thanks
since I have deleted the A/C, heat and cooling, I should no longer need that check valve and could just place a coupler there correct?
Thanks again

IIRC you can just cap off the nipples on the plenum and be done with it. The other end does go to cruise.
