OK which is the correct way to set Fuel Pressure on an EFI engine. I was always told to disconnect the Vacuum line and set the regulator to 40 PSI then put the vacuum line back on and it should drop to about 32 PSI.
I have also been told to set the fuel pressure with the key on engine off and set the pressure to 35psi-45psi.
Which is the correct way and what should the pressure be running at idle.
