Key on engine running fuel pressure

1999 Ford Ranger Pickup Truck - 6 cylinder, 3 liter Flex Fuel System (FFV).

I am reading a pressure of 55 - 58 PSI when measured at the fuel rail on the engine. I know my pressure gauge is okay.

What should the fuel pressure specification be for an FFV vehicle for key on engine running? What is the fix - replace the pressure regulator and the fuel rail, or possibly just the pressure regulator, or?

Thanks!

Center of spec for a 98~2000 Ranger 3.0 FFV is 55 PSI.
For all other 98~2000 Rangers except 3.0 FFV, the spec is 65 PSI.
