What's this hose for???

my 95z stock lt1 motor... on the passenger side valve cover i have a hose coming out of it going to the passenger side of the throttle body/intake. whats this hose do and anyone know where i can get a replacement at??? when i came home i noticed a huge slice up the side of it and the hose is as stiff as a brick. guess its time to start replacing these old crusty hoses lol

my assumption was its for some kind of vaccum or something but i couldnt find a picture of it anywhere in shoebox's site

It's the vacuum source for the PCV valve. You should be able to get it at any parts store.

If not, it's GM part number 10128365.
