I am just curious as to what my Fuel pressure should be set to at idle?? I am BPU++++++ including cams just to show how ++ I am, and have a -6AN fuel line system tapped into the factory rail and through a SX Pressure regulator. I do have a fuel pressure guage to reference my pressure. What should the pressure be at during idle? I read somewhere else that it should read 40-45psi when the ignition is on but car not running (I think they called that static??) and the vacuum hose detached from the regulator. Is this correct and should the psi remain the same once the engine is actually started?? If the psi changes after the car is started, what psi should it change to?? Thanks and I hope that made sense...lol. Peace!
