Could there be air in the line up to the gauge? You might try loosening the line at the gauge with the engine running, especially when it reads zero. That way you can bleed the tubing and verify that there is oil at the gauge.


X2, and I hope you put some loops in the copper line where it comes off the engine. If not the torqueing of the engine will work harden the copper and in time it will crack.
