This has been bugging me for several years; every time the light switch is "ON", the fuel gauge level jumps up almost 1/4 tank.

I have a Getty 5 gauge dash: Clock, Speedo, Tach, Oil Press/Temp, and Fuel/Voltmeter.

All the gauges share a common ground and common voltage source for the gauge lights; I'm wondering whether one or both need to be isolated to prevent the interference?

Need some electriccal input here... (IMG:style_emoticons/default/smile.gif)
