For a naturally aspirated combination, you'll want to shoot for 38-42psi at idle with the vacuum reverence line disconnected. I generally find that most cars respond well to 38-39psi.

You may not be able to install the unit without removing the upper intake. You can install a guage connection without removing anything from the motor. That is needed because you need to adjust this with the motor running.

I'm restoring my 88 fox body 5.0 and adding little performance upgrades where stock components were. And I've heard that I should get a fuel pressure regulator, I would like to know the advantages of having one, and if possible any installation guide.

Being able to adjust your fuel pressure will allow you to fine tune your air to fuel ratio to get the most power out of any performance parts you have installed. There are some install instructions here: http://www.bbkperformance.com/download_file.php?pvk=338
