Joseph_H,

The fact that MB don't put values on the gauge gives you an indication of how important they think they are..........


If you know the pressure from a mechanical gauge, and nothing terminal appears to be happening in the engine, why not set the needle to max at that point?

You have now calibrated your gauge. Good nights sleep should be available from now on...............
