    If your digital gauge is accurately showing the correct amount of fuel, the problem isn't your tank sender.

    This.

    The analog gauge is redundant to the digital, SC gauge. The SC gauge tells the analog gauge what to display. Could be an issue with the SC gauge... wiring between it and the analog gauge... or the analog gauge, itself. Try connections, first - and/or tapping on the analog gauge.

    Probably not, possibly fuel slosh . It happens with float style
