I have two questions.

Did the float still float even when you heard some gas sloshing in it? The float is not going to sink from 3/4 tank to 1/4 tank unless it is full of gas and then I think it would hit bottom.

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.
