When I was cleaning out the tank for my '49 B1PW, I tried a sending unit from an earlier VW Bug (6-volts even), and found that it fit the tank opening and studs nearly perfectly. I didn't hook it up electrically, but they may work with some electrical finangling. Possibly worth a try, there must be zillions of them available yet.
