    Mechanical oil pressure gauge
    « on: October 23, 2011 - 05:06:34 PM »
    Looking at the clear plastic hose going from the back of the motor through the firewall into the dash I can see air gap. Is that normal? Or, do I need to bleed all the air from the system?

    I've had several over the years . Always had air bubbles , never thought much about it though . I suppose since air will compress under pressure it could effect your reading till the air got compressed . Then the reading could change with RPM's but I have to think you're ok unless you have to be to the pound for some reason .  :clueless:

    I have bled them out in the past only to have the bubbles return so don,t wast your time .
    The way I figure it is even though the air will compress it will still have equal pressure on either side of the air bubble
