Fuel Gauge (Dots) Problems?

Next time the display messes up, check the Range display. If it matches the gauge (ie, close to zero), it's probably the tank sensor or wiring (a not uncommon problem as mentioned above). Else I suspect a bad gauge, possibly a common ground/supply for the dots.

If you never been inside the tank. It has 2 float sensors. One on each side. They're both a resistor type of sensor. As the float moves up and down. The other end of the arm moves on a resistor grid, changing the voltage signal back to the gauge basically. If one of the floats has absorbed some fuel. It will not float as high. Giving you a low reading. Or if the arm is bent. It might not be going high enough to trigger the last full light on the gauge.

I think you're right. My tank is pretty much full and the last few lights never light up.
