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. Was this reading taken with the tan wire unplugged? yes, the tan wire was unplugged. I clipped the red lead to the pin on the in-tank sending unit and touched the black lead to the tank itself
I tested the tan wire, grounded to the gas tank, with the key on, I get a reading of 69 ohms (coincidence)?? how was the meter set up (1 lead to tan wire and the other lead to the tank (series))? Yes, I clipped the red lead to the terminal on the tan wire and touched the black lead to the tank itself.

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