Does anybody know the efficiency of the 1g nt fuel pump? I beleive at idle fuel pressure is 45psi. Whats the highest pressure the nt fuel pump can pump?

According to my chiltons for the 90-94 nt it says to "Locate and disconnect the vacuum hose from the fuel pressure regulator. Plug the end of the hose. Measure the fuel pressure and compare it to 47-50 psi." Next "Reconnect the pressure regulator vacuum hose, then measure the fuel pressure and compare it to 38psi". I do believe that the car should be Idling during these tests, and always check for leaks before you start the motor.

You don't understand my question. With a rising rate FPR fuel pressure can be risen. What is the highest pressure the nt fuel pump can pump?
