Best Fuel Pressure gauge? - Page 2

Not sure if it applies here, but I had a lot of experience with gauges though in an industrial setting.

The only reason manufacturers ever gave me for choosing liquid filled was to dampen needle flutter if that existed in the system. None of them ever mentioned the gauge being more accurate or being built better.

The comment about temperature affecting liquid viscosity was interesting and could make sense. Unless there's been a major change, the liquid is glycerine which is naturally a pretty thick thing. I've never seen anything about heat ramping for the viscosity but would think it would be much lower than something thin like water.

clearly not much based on the rest of your reply but we expect nothing less from a "troll" and a "goon" that thinks he knows!

Ed,
Have you ever been treated for ASPD?

frank you don't have much time left on this rock, why are you wasting it, you have nothing to add here.

I'm seventy years young, a cancer survivor, retired from a great career with a beautiful family including a grandchild and one soon to be born. I live in the beautiful community of Charleston SC. What could be better?

You are correct about why the fluid is in the gauge. If accuracy to the nth degree is needed get a NIST traceable certified gauge.
