Erratic Fuel Gauge

The fuel gauge on my 50 Deluxe is pretty erratic, ranging from the needle bouncing back and forth to just sitting on E and not moving at all. Since I recently had the sender replaced, I believe the problem must be with the original factory fuel gauge. I'm considering installing an auxiliary gauge, rather than tempting fate by trying to work behind the dash on the original gauge. I'm wondering if a 12 volt gauge will work with a 6 volt sender. I've looked online and found opinions that say it will work because the sender works on the changing resistance in the sender and that the voltage doesn't matter. What do you think? Also, is the resistance range of the factory sender 0-90 ohms? Thanks
