    Fuel Pressure

    Hi!

    I have a RIVA FPR set at 60psi on my ski... Sometimes, when I start the engine, it's showing 59psi or 61psi and that's affecting my afr a bit (that's normal) but why is the pressure changing like that... +/- 1 psi... Can the atmospheric pressure affect the FPR?

    Thanks for the help!
