    Fuel pressure?

    How many lbs of fuel pressure will I need to supply my nitrous selenoids with??
    I'm almost done with my standalone setup, just want to make sure how I want the fuel pressure regulator to be set at..

    Thanks guys!!

    By the way.. How much pressure does our trucks stock fuel pump produces?? Maybe the stock fuel pump won't need a FPR right? Please correct me if I'm wrong..

    I run mine at 56 PSI through an Aeroforce fuel pressure regulator. Not sure if its 100% necessary as long as you put the right pills in the lines.
