Ok.....put a mechanical gauge on it to test......65 at idle. Now, to get a new sender, or gauge package. So....it looks like turning the adjuster in 1/2 turn gained 5 pounds of pressure.

I'm coming over to steal yours to see if it's the sending unit or the gauge

Alright, a few more observations. I replaced the gauge, and sending unit, and now have 62psi at idle, and 58 at wot. The 65psi figure I stated I had originally is incorrect. I was using a mechanical gauge, and it only went to 60psi. I just figured a little past the 60 mark was around 65. So...I put 1/2 turn clockwise in the regulator in the module inside the tank, and it raised the pressure to 62psi. I think that should be about right.
