I was ordering Christmas presents for my 57 ranchero, I'm going with a 22 gallon fuel cell with a sending unit to the fuel gauge. The parts shop says there is 3 different types, one works between 70 and 10 ohms, one is 0 to90 ohms,and the other one is 240 to 33 ohms resistance. I looked on the gauge cluster and didn't find anything. Anybody know the answer to this? thanks in advance for your help, Mark
