I am out of my league in referring to physical principles, but I think that those mechanical gauges are related to a Bourdon tube, which pre-dates the Jet Age?
Maybe a rocket science class would help some of us understand the workings of a fuel gauge (even if we understand the steps for a diagnosis of a fuel-gauge problem).
