    Key on engine off 35-45 psi.
    Engine running vacuum hose attached to regulator 30-45 psi
    " " detached 40-50 psi

    The hold pressure at schrader valve engine off should be 30-40 psi

    This is what i have from the board.

    Key on engine off, line primed, stock fuel pressure regulator, 40 psi +/- 1 psi. If you have an adjustable regulator, set the pressure static at 43.5 psi.
