Jerry, does voltage really affect a gas gauge? My '36 Chevy pickup is restored now. But when I was in college 40 years ago I ran it as a Chevy V8 powered jalopy with a 12 volt system. The gas gauge worked equally well on 6 or 12 volts. An old friend told me that the gauge has 2 coils that pull the needle in opposite directions and that system works independently of voltage. I never looked into his explanation but the voltage seemed to make no difference.
