Where to test fuel pressure for Spica system

I just swapped out y 3 port for a 2 port fuel pump. Ran a return line back to the tank. I want to make sure I am operating within range of keeping the pump healthy and engine happy. Where should I install "T's" into the lines to check pressure? And what should those pressures be? I believe that after the pump restrictor outlet I should put one and the pressure should be about 17psi? What about before the pump?

Thanks!
