GM 366 fuel pressure?

I guys, having a hard time finding what my fuel pressure should be on my 1992 GM topkick with a 366 TBI. I currently have 30 psi across the board. Idle and high idle. Just trying to verify if this is correct? It appears the pickups were in the 9-13 range? And there are other systems in the 50-60 range? But haven't seen anything listed @ 30 psi.

    My '95 366 runs at 30 psi. Has the 295 TBI unit on it. See here https://www.dynamicefi.com/TBI_Fueling.php

    Thanks heymccall. This truck is a bit of a pooch, and I'm just trying to verify that everything is set as it should be.
