fuel gauge & sender

[verdell]

Does anyone know how to make a 0-90 ohm fuel gauge work with a 0-30 ohm sending unit?!?? I think it's just a matter of installing resistors but not sure...PLEASE HELP asap!!!

I'm not sure that you can. If you add a 60 ohm resistor then the sending unit will always have at least 60 oms of resistance so it would have a working range of 60 to 90 ohms instead of 0 to 90 like you need. I could be wrong though.
