OK Guys, I tested my sending units.
When the float is up it reads 96 Ohms, when down it reads about 1 or 2 Ohms. that Checks!
I fueled my truck up yesterday so my float should be riding high in the tank.
The sending unit in my tank is currently reading 69 Ohms. My fuel gauge reads 1/4 of a tank (bogus). At 69 Ohms shouldn't my gauge be reading up around 3/4 of a tank? The gauge is not properly interpreting the resistance that the sending unit creates.
I tested the tan wire, grounded to the gas tank, with the key on, I get a reading of 69 ohms (coincidence)?? Shouldnt I get a low number, close to zero?
thanks,

I think my sending unit is good. Would you agree?
