Hi,

Here are the specs for fuel pressure:

1994 Nissan-Datsun Truck Pathfinder 4WD V6-2960cc 3.0L SOHC MFI (VG30E)
Pressure, Vacuum and Temperature
Vehicle Powertrain Management Fuel Delivery and Air Induction Fuel Pump Fuel Pressure Specifications Pressure, Vacuum and Temperature
PRESSURE, VACUUM AND TEMPERATURE
With fuel pressure regulator vacuum hose
Connected. Approximately 235 kPa (34 psi)

With fuel pressure regulator vacuum hose
Disconnected. Approximately 294 kPa (43 psi)

_____________

The regulator should be on the fuel rail. It will have a vacuum hose running to it.

Let me know if this helps.

Joe
