new idea...
we all got a guage...supposed to oem. Even my old car is pretty darn good with it.
a low light comes on.. and then, yep. I run out of fuel.
why not have that known movemnt of callibration be LCD, as in gallons.
a start point for fuel, a reset odometer 0...
didn't an early 80s thunderbird play with that..
gallons end point subtracted from start, figure it out with end odometer.
