Need help with figuring out a broke hose

[escort1991]

Alright, so when I was at Big Nate's place, he found a hose that has a connector that is broken. Car is an 04 mz3 2.3L. Went to a Mazda dealership and couldn't see it on the microfiche. But, can someone tell me what this hose goes to and it's purpose, maybe a part number?

Brake booster vac line?

Need pics of the other end it connects to. Appears to be a vac line from where it starts, but the real clue is what it attaches to near the firewall. Brake booster would be a good guess like Dan said.

It is a break booster line. But what i think he is asking about is what would the part that is broken be called? the little thing coming out of the throttle body. That little bit of hose in the pic with the stainless clamp on it was there to rig it to work and not through a CEL.

The broken part would turn but not come out. Not sure if it is part of the throttle body or if it is part of the hose/line set.

The drops down behind the battery and connects to the firewall. Tried to look quick inside the car, but couldn't find where it came out.

So, finally found out what this is. It is the brake booster line. $137 from Morries.
