I was looking at my engine today and I noticed this. It was a small wire or hose, it looked like a wire, but it broke and there was no wire in it so I"m guessing a small hose? When I grabbed it to look at it the small hose snapped. The small hose was coming out of the fire wall and connected to this thing. And it was sitting just behind the intake. It looks like the end that was missing something is larger. Is this a vacuum line? Where does it go? And can I reconnect the two pieces of small hose? or what? Thanks!
