New OE Z32 fuel pressure regulator. Fits all 1990+ Nissan 300ZX models.
The OE fuel pressure regulator should maintain fuel pressure at ~36 psi at idle with vacuum reference attached, 46 psi at static manifold pressure, then increases fuel pressure 1:1 per psi of boost. The most common failure of the OE fuel pressure regulator is a fuel leak in which case it should be replaced immediately!
