This is my first car so I don’t know too much about really anything car wise. I was cleaning my throttle body and as I was finishing up I think I accidentally pulled this hose off of the connector end it was on? Upon further inspection I saw that the end was really short and it seemed like maybe it was once longer but it I guess rotted away? Is this a correct assumption or should I get this checked out further.

Also there was a lot more brown gunk in the hose earlier but I was picking some of it away with a pair of pliers
