    Fuel sending unit question

    Does anybody know the Ohm range for the stock sending unit. Mine is long gone, and I want to install a RCI Aluminum Fuel Cell. The sending unit on this tank is 0-90 Ohms. Will it work on my stock Smith gauge?

     

    Thanks

    It should. The actual resistance is not very important.

    The sender sends back a voltage that represents the RATIO between full and empty. For a 12 volt system, a full tank willl send 12v - 3/4 tank will send 9V - 1/2 tank will send 6V - 1/4 tank will send 3V....get it? The actual resistance shouldn't matter, it's the RATIO that's important.
