My fuel gauge has always been wrong on my 1995 Firebird. When the gauge comes off full, I know that I need to get gas fairly soon for street driving and immediately for track driving.
Yesterday through the use of a scan tool, I also learned that my water temperature reads way too low while also learning that GM has two water temperature senors in the car - one for the ECM and one for the fool behind the wheel. The ECM sensor seems correct and the in-dash water temperature gauge is wrong. Should I be treating these two problems as separate or is it possible that these are related? |

I think the main problem with the fuel guage is the shape of the tank. Since the tank is bigger at the top it may take 5 gallons to drop the float a few inches. Meanwhile at the bottom of the tank, a 2 gallon difference can lower the float a similar amount. Of course the float isn't calibrated for this difference and it drops at a faster rate as the tank approaches empty.
