My experience is that the electrical sensor for Oil temp and pressure are less likely to leak than a capillary tube that is subject to vibration. I have only used electrical sensors to measure all engine fluid parameters (except manifold pressure) and have had no problems. I don't like liquids in the cockpit.

Group,

Fixing to get oil pressure gauge and am concerned about the quality of the electrical sending units. How likely are they to leak or come apart and cause complete oil loss?

Using a mechanical gauge eliminates the sender but uses a capillary tube that can break. What are the pros and cons to electrical gauges?
