Customer Question

I need to if there's any tech. That can show me in the wiring diagram the fuel sending unit.on a 2001 s430 mercedes. My fuel gauge shows it full when it's empty. Changed the the fuel sending unit also swapped a cluster and it shows the same.when I move
sending unit out gas tank it does the opposite effect. So in other words it when I move move the fuel level down it moves the gas gauge to almost full.and when I move it up it shows empty. So with the research I have done it must be ground issue but it seems
like I can't find anybody that has this kind of knowledge I don seems there knowledge poeple with this website.
