Second, have you tested the resistor? Pull the resistor from the back of the fuel gauge and test it. It should read in the area of 85-90 ohms. If it is anything less, such as 25 ohms, your resistor is bad. It is one of the more common reasons why a fuel gauge will not go past 1/4 full regardless of full level.
The tank was reading empty. When I removed the float and moved it up and down, the gauge went from empty and back. The sender is only 6 months or so old, I think it progressively filled up enough to make it sink.

I had it sitting on a towel that go wet from gas when I unhooked the fuel line, so I'm hoping enough leaked out to make it float in the tub. The bubbles told me that it was filling with water, but very slowly.

So I won't know for sure until I get the new one. Hoping this fixes it.
