Mystery hose on top of supecharger

[lofa129]

I was in the process of changing rear spark plugs when I leaned a bit to far over and cracked a tiny piece of plastic with a hose attached. See the picture below.

Any idea what it is? Im assuming its important considering its connected to the supercharger. Any help is appreciated, thanks guys.

You can get them for like $12 at the dealer.

GM Part #24503488, $6. Also known as vacuum manifold.

You made a small vacuum leak, so it's safe to drive, just keep your foot out of it until it's replaced.
