Coolant expansion tank tube routing?

Can anyone tell me where the tube circling the red connects to, I’m putting my engine back together post a header install. Thanks.

that drops down on the side of the shock tower, if you look a little bit down the shock tower you'll see a slot where that fits.

Look where the hose disappears in this photo near the frame rail, you will see a box shapped cutout, route it down through there.

To state the obvious, it doesnt connect to anything. Its a vent to atmosphere tube.

Good to know. I have to replace my expansion tank and tubing as well.
