1991 4.0 V6 Fuel Pressure

I have been having a problem with hard hot starts for a while now, and Im looking to replace my fuel pump and/or fuel pressure regulator. I checked the pressure and it looks to be 28 at idle and about 26 at 3000 rpm. I couldn't find a definite answer to whether or not this is low, but the consensus said it was.

What should the fuel pressure read on my fuel system??
