oil pressure indication

[Russell320]

That's why I have both instruments in the cockpit. The electronic sending units do not do well with the vibration (buzz) of the Rotax engine whether it's mounted on the firewall or the engine. There are newer sending units available. But the piece of mind I have with the mechanical unit gives me great comfort when I question the other reading.

You might check with John McBean at Kitfox. He has a nice sending unit that fastens to the fire wall. Don't know if it is compatable to the gauge or not.
If you do use a manual gauge with a copper line,make sure you have a loop in the line as copper can become brittle with vibration and break. The loop will also give you a steady pressure reading.

I definately put a loop in the line as well as anchor it with some adel clamps. I am also going to check in to some small stainles steel line. This would hold up much better. Thanks for the suggestions.
