It takes a little more or less fuel to ll up than the
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 ll the tank.
The gage moves a little when you turn a corner or

The gage doesn’t go back to empty when you turn
off the ignition.
