yellowblue Listed are four situations you may experience with your fuel gage: D The gage moves a little when you turn a corner or speed up. D At the gas station, the fuel pump shuts off before the gage reads F (Full). D The gage doesn't go back to E (Empty) when you turn off the ignition. None of these indicate a problem with the fuel gage. D It takes a little more or less fuel to fill up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank's capacity to fill the tank. 2-63
