I'll have gas with me but I don't have the regulators that I bought from Vicegrip, Sloan does and he will be up on Saturday.

Yeah that is what David Glen said when I spoke with him. Even measuring is a problem

We made a loss table by opening, measuring, closing, venting, repeat to see loss at each pressure due to measurement. Between 12 and 22psi in the 150 to 210osi range. No loss on fill, of course.

Is it possible to plumb a gauge in-line to easily monitor PSI?

The gauge I have actually is designed to be in line to the tank

I'm talking about a guage that would be inline with the plumbing on the car. Something that could be looked out without using a handheld guage. I'm not familiar with these remote reservoir shocks, so maybe this is not doable.

oh - interesting concept. I have never seen anything like that. I bet there is some sort of pressure gauge that could sit on the test valve on the canister - maybe even one with the ability to have remote monitoring.

You have too much time on your hands. All that and you still end up with a guess A more educated one but a wider bracket than overfill and drop to target
