I have a generator I would like to add remote fuel level and oil pressure displays to.

My original idea was to plug the existing oil and fuel signals into an arduino, have it display on a screen, then somehow duplicate these resistances to feed into the generator so it doesn't generate crazy alarms.

The fuel sender is a 33-240 ohm sensor and the oil sender is 0-90 ohms. I was thinking of either using a programmable potentiometer or stepper motors attached to physical knobbed potentiometers but I am afraid too much current would pass through these (33ohms at 12V is 363mA, which would be 4.36W dissipated through the potentiometer).

Is there some way I can do this, or would the current passed through these not be that high?
