How do i change this hose???

[JLHollowX13]

so i have been replacing hoses as they break from old age and me working around them. i now need to replace one that i have no idea how to get to. it is the one that goes between the intake manifold, by the pcv valve and connects at the top of the throttle body. how do i change this one???? ive been out there for HOURS trying to figure this out. is there any easy way? i cant figure out how to unhook it from underneath the intake manifold, and if i do get it unhooked i dont know how i would get a new one on. im stuck.

thanks for any help!
