I did the test yesterday and this are the result
- fuel pressure at idle and vacuum hose of the fuel pressure regulator connected 33Psi
- fuel pressure at idle and vacuum hose of the fuel pressure regulator disconnected 42 Psi
after that I turned off the engine and reported the pressure the result was
at 4:36 pm the pressure was 33 psi
at 4:41 pm the pressure was 29 psi
at 4:44 pm the pressure was 28 psi
at 4:57 pm the pressure was 26 psi
at 5:13 pm the pressure was 16 psi
at 5:18 pm the pressure was 14 psi
at 5:25 pm the pressure was 8 psi
at 5:37 pm the pressure was 5 psi
the next day the pressure was 0 Psi
the fuel pressure regulator is good it does not let fuel goes back to the tank when the engine is off
