Thanks to all who responded to my email last week. In troubleshooting my fuel gauge problems on my '64 this weekend I put a variable resistor where the fuel sending unit would normally go. This allowed me to verify that I do indeed have a bum sender, but it also allowed me to note the various resistance values that it took to drive my fuel gauge to various settings. Full = 5.5 Ohms 3/4 = 12.5 Ohms 1/2 = 19.5 Ohms 1/4 = 29 Ohms Empty = 57 Ohms I don't know how typical this will be for other Mopars, but that's what it is on my '64 300.
