Now that I dropped the tank from my 1946 Roadmaster, might as well ask about the fuel sender. When I bought my car as a project in 1997, I recall the seller told me the tank that followed the car wasn't original. He didn't know what it was, other than it came from an American car, maybe Cadillac. I measured the ohms of the sender to be 2...39 ohms, that is, nominally something like 0 to 40 ohms. It has a cork float, and the tank has a drain plug, so it must be pretty old. Is this the ohm range that the Buick gauge is designed for?
I had this sender working with the original gas gauge, until the gauge broke (the needle dropped off the shaft). But even when it was working, the needle kept swinging back and forth without a steady reading. I thought it was due to the voltage regulator (from 12 to 6 volts) that a friend of mine made for me. Now, I recently met a Swedish guy at a show who told me he's running full 12 volts to the 6-volt gas gauge, and it works fine. Any thoughts or experience?
