It's not in the red area, it's further back towards the firewall, by the ignition coil pack.
It controls the flow of gasoline tank vapors into the intake manifold. You do not have to remove the intake manifold to get to it.
There is nothing in the red area that has vacuum in it (except for the intake manifold, but I can't see it leaking bad enough to make a hissing noise).
