    Kind of a dumb question but here goes. What is the differance between liquid filled and standard fuel gauges?Other than one has liquid in it.Is one better than the other?

    I think the liquid in a gauge acts as a damper for the needle. Slows the movement down when it goes from one extreme to the other.

    If you use a liquid gauge near heat it will read incorrect, Ask me how I know.
    The sealed liquid inside gauge heats up and expands and moves bourbon tube and reads incorrect. You could drain some of the liquid from gauge and it will read better. The liquid dampens the swings of the needle in the gauge.
