Vacuum line to FPR source?

I can't seem to find a decent enough drawing to show this detail: Does the fuel pressure regulator vacuum line come from the "ported" connection under the throttle body or the "open" one at the rear of the plenum? This is on a '88 L98. I assume the other one is for the EGR right?

Thanks for the help!

The vacuum hose for the FPR goes to the rear/right(passenger side) of the plenum, and the EGR goes to the one under the throttle body.
