I'm guessing you are referring to a vacuum manifold right? If so give this a look. I picked it up so I wouldn't have to daisy chain a bunch of t's. Still building the car up so haven't used it yet, but it comes with extra plugs and junk.

I've been running a switch similar to this one on my car for many years with no issues

You can get a Hobbs switch at your local parts store. Mine activates my second fuel pump at 4psi.

If you're looking for a vacuum operated switch rather than a pressure (boost) operated switch, this should get you started:

Check out the "Low Pressure and Vacuum" link, and then go to the last page of the PDF file when it loads. It will show you the available vacuum operated switches, with part numbers.
