So i may have a 0-50ohm variable resistor in my fuel sender instead of a 0-90ohms resistor?

That would suck, but at least i know.

There is no one who has built a voltage to current mirror circuit to adjust the currents to similar levels as a 0-90ohm resistance circuit?
That seems like it would be relatively easy to do and its just a couple of transistors.

Its been 35 years since i last calculated an voltage following current mirror so if someone has a working circuit i would be happy to borrow it... anyone?
