55 Ford, Fairlane, 272, converted to 12V system. The fuel gauge on the dash will not read properly. Goes to full when tank is full, the needle will fluctuate down and up when driving, going from full to half or quarter then back to full. I've put in a new tank, sending unit, checked wiring going from tank to gauge, not grounding anywhere. Is the 12V conversion an issue with the gauge. The needle on the gauge jumps a little when going up from empty when I first turn the ignition on. Any insight on the issue is appreciated. Thanks in advance.
