    Bmw 850 fuel gauge question

    My fuel gauge isn’t working, the gauge it’s self is fine so I think it’s the sender unit or something along those lines, can someone point me in the right direction?

    over time, the wiring to the fuel level float rheostat inn the fuel pump carrier gets brittle and may break off is one cause. The other can be one or both fuel float assemblies being faulty. You can check the resistance across the pins to see if it is reading correctly.
