I was asking summit racing about their
mechanical gauges, wondering if the price included all the necessary
parts. they told me that the oil pressure and water temp hook up directly
with an 1/8th" line that I cut to fit. I questioned whether the water temp
would work that way since water wouldn't be circulating thru the line. do
mechanical temperature gauges work that way? I assumed there must be
a sealed , fixed length bulb/line arrangement that converts temp into line
pressure?
what are the pros/cons of using mechanical vs.
electrical gauges? I have some of them currently in my plane but will need
gauges to run the engine initially for ground tests, and hate to pay for
duplicates, so leaning towards the cheaper mechanical
gauges. kevin
