Been a while since I've done maths/ohms but

Assuming the float is usually supplied 12v

Vn would be full12v/40ohm= 0.3A @gauge

12v/290ohm=0.041A @gauge

If you reduced the supply voltage (chuck a potentiometer in and adjust to correct voltage)

With mitsi float

5v/17ohm=0.29A @gauge

5v/120ohm=0.041A @gauge

I could be completely wrong but that works in my head?

I'd be tempted to chuck an electronic 5V voltage regulator in at the sender to try that out.

Just thinking as I type/tap though, do you actually have 12V at the sender rheostat? Maybe some voltage is lost at the gauge via a movement coil?

Only had my sender apart couple of days ago funnily enough, never chucked voltmeter on it tho as was obviously a holed float and ohms were ok...
