The compression fittings will be the failure point. They won't like the temperature changes and vibration conditions on soft copper. Flare fittings would be a better choice. The higher pressure oil sensor should be grey, .8 bar normally open, closing with sufficient pressure.

        Snazzy for sure ~ But ~ In any of these adaptations where the Sensors are located @ the End of a Path

(Which in most cases is Conveniently Located Above the Eng') Instead of @ a Flow By Location, how can one

be sure they are receiving Real Time Info Or Possibly Even Not Oil Info @ All but Maybe the Pressure & Temp

of a Trapped Air Pocket ~
