38 PSI with vacuum line on fuel pressure regulator. 42 PSI with it off. That is what mine is.

Just an addition, according to the FSM, it can be as low as 31PSI with the vacuum line on an still be within spec.

Ignition On, Engine Off: 41.0 to 47.0 PSI
Engine On, Regulator Vacuum Applied @ Normal Idle: 3 - 10 PSI less than Ignition On, Engine Off.
