Leaking line?

Truck starting idling like it was about to quit and I could hear a loud hissing sound from under the hood. Located the sound. Not sure what the line is called, I have circled it in the photos below. It is cracked where the black part connects to the intake manifold. I assume this is why my truck wasn't running right. Can someone help me in identifying the name of the part so I can get a replacement? I think it is a vacuum line of some sort. 1998 Tacoma 3.4l

 

hard to tell but im guessing the pcv valve hose but follow to where it goes to and that will give you its name

 

Raise your hood and prop it up. Now look up at the underneath and they'll be a vacuum hose diagram. Look see what you've got there and replace it. I had a big OCD rat eat all of my hoses and lay the others it didn't eat in nice little symmetrical piles on the top of the engine once. So I've since had to replace every hose and plug wire and some of a cable run to the passenger side headlight. All rats and squirrels are subject to being shot on sight around here.
