    Ok ok, using a Scott air pump on a Equalizer shock

    This is going to sound dumb as I don't know the answer to this question, yet I've been able to dial in my bike decently well....

    When you use a shock air pump on an air shock and you get to the right pressure, are you supposed to pump a little extra air to compensate for the air that's trapped in the shock's hose?? We all know that 'hissing' sound when you unscrew the pump is from the air escaping the hose, not the shock.

    I'm asking because obviously, when you re-attach the pump, you air pressure reading will be less than what you initially put in.

    Thanks.

    Shouldn't have to pump extra. when you pump the shock and hose have equal pressure. Assuming everything works right, the shock should seal before the hose is unscrewed, thus releasing the pressure in the hose. When the hose is reconnected, the hose will re-pressurize from the shock, causing the pressure to lower in the shock somewhat.
