Vacuum hose connection or not??

[svxstarship]

Removed the intake manifold to replace all the dried out hoses etc. Before starting I noticed the pipe off the back of the passenger side manifold had nothing connected to it. Does a vacuum hose connect to this pipe ( see pic ),
or not? ps, the rubber hose above it in the pic connects to the fuel rail so it's not that. This is on my 92. Checked on my 96 but the pipe is not there.
