If the resistor element was open near the center, it could send something weird.
It will have to be removed from the tank in any case
.
i have a similar problem with mine, so I just keep the tank full and watch the trip mileage add up.
Hope this helps.

Did this get replaced recently?
Fuel level senders typically work by changing the resistance (and therefore current) depending on the fuel level determined by the position of the float mechanism in the tank. Since the guage you are describing is working exactly opposit to as intended, is it possible that an incorrect sender was installed, or, if there are 2 terminals on the guage, have the wires been switched so that the current is going through the wrong way?

Gauge reads full when tank is empty


You have a bad ground, you will have to remove the fuel tank and check the connectons on top of the tank, probably corroded. You can clean the terminals or change them.

You need to check voltage at the gauge on the dash.
They would stop at random places with the key off.
You can disconnect the sending unit in the tank and ground the gauge to test.
Some models read empty with high resistance from the sender, some are opposite depending on the sending unit. The sending unit in the tank is a resistance bar for the ground circuit.

Fuel gauge reads past full all the time


when the tank is full the resistance is low so the power through the gage make is read full
as the tank empties , the resistance increases so the less current means the gauge reads less until empty there is little or no power , the gauge reads empty
simple check , turn the ignition off, no power , no gauge reading

2002 Chevy Suburban: Fuel gauge reads empty, tank is half full


Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.
