I replaced the valve cover gaskets on this 1985 300zx non turbo, and the two hoses in the pic circled in red have dry rotted and had to be cut off.

I tried to use regular hoses but they wont fit due to the bends and curves. Can someone please help with the part number
and identification of these two hoses? They come off the air intake, one goes into the valve cover, but i dont know what it is called that the other one goes into.
