I am looking around my engine compartment. (1987 yj 4.2 Automatic) Replacing a few hoses and I find this round piece with connections for two hoses. I know previous owner disconnected a lot. Is this all right like this? Does it need to be capped? I would search the forum and not bother the forum with this but I don't even know what that part is called. Thank you in advance for your time.
