NHTSA's summary

This Preliminary Information communication provides information to the technician about vehicles that have an inaccurate fuel gauge. Technician should drive the vehicle to duplicate the concern. The fuel gauge will have a tendency to falsely indicate a lower fuel level than what is actually present. The fuel gauge will take a few minutes to show the correct fuel level. On vehicles equipped with an automatic transmission no buffering takes place when the transmission is in park or neutral. This is a normal characteristic and no repairs are necessary. On vehicles equipped with a manual transmission the fuel gauge is buffered in all gears and neutral. There is a timer which starts to count up when the clutch is depressed. When this timer reaches its calibrated value the buffering stops. This is a normal characteristic and no repairs are necessary.
