I recently fitted an after market fuel gauge & sender kit, marked as 12 volt, I assumed it was just the illimination that was 12volt, I have this on the car & working, but before fitting I had the sender wired up to gauge on the bench, when sender was 1/2 way on 12 volt 1/2 tank indicated, but with 6 volt it was down to a 1/4, also it is polarity sensitive, so my kit must contain a 12 volt device , Zener or similar diode, I tried various resistances to try & balance but gave up, at the moment I have a small bell battery just feeding the gauge until I get time to re calibrate the kit. at least at the moment I have an accurate means of knowing my gas level,
