It connects to the intake manifold- it might be a pain to get in there and remove the old hose.

These threads will give you a better idea of where the hose runs to:

If you're having a tough time accessing the underside of the intake manifold where the hose connects, you could always try release the hose clamp around the old valve and placing the new one into the old hose.
