I'm learning a lot, and it's kind of embarrassing. After building and flying for many, many years, I never knew about this. Thanks for helping me out.
Due to the price of these gauges, I plan to just flush it out along with the connecting tubing. Anybody have any recommendations on a solvent to use so I don't melt the case?
