Its usually a variable resistance sender.  Should be able to use just about anything and feed it in on a spare AN input.  Will need a pull up resistor between the signal and 5v reference as most are 2 wire.

Then just see what it does outside the tank and create a calibration based on that.  Most older units are not going to be a linear calibration so you will want to check multiple points from empty to full.

Outside of that it should be relatively easy to get it on the CAN bus and on its way to the dash.
