You don't need any complex circuits or modifications. Just connect 1500 ohms from the fuel tank sensor output to ground. That would give 132.2 ohms when full (145 ohms from sensor) and 21.7 ohms when empty (22 ohms from sensor), close enough, I would think.
Edit: To get closer, you could also add a 0.3 ohm resistor in series with the sensor output along with a 1470 ohm resistor from the sensor out to ground. That would give 132.3 ohms when full and 22 ohms when empty, as desired.
