Why is my gas gauge stuck past full?
The most common cause of this type of gauge to read over full is typically due to no ground at the sender, an open circuit, or break in the wire going from the gauge to the sender.
How do you fix a sticking gas gauge?
Check the grounding wire on the fuel gauge. To do so, connect the negative jumper cable to the vehicle’s frame and the positive cable to the fuel gauge’s grounding terminal. Turn the ignition to the on position and look at the fuel gauge. If the gauge is not working, then the grounding wire needs to be replaced.

How do I know if my fuel float is stuck?
One of the signs that the carburetor float is sticking is when the engine will not idle. The float is not letting enough fuel into the reservoir, allowing for a constant idle of the engine. The carburetor float is stuck in the closed position, and only a small amount of fuel is seeping into the reservoir.

What would cause a fuel gauge to peg way past full?

What causes a bad gas gauge on a Chevy truck?
A poor ground or loose connection to a gas gauge is just as likely to cause problems as loose or dirty battery cables assuredly will with your starting system.
What to do if your gas gauge is not working?
If the gauge still reads incorrectly, the wire from the tank unit to the gauge may be faulty. Check by using a jumper wire to ground the tank unit terminal on the gauge (the one not connected to the ignition). If the gauge now reads empty or below, the problem is in the wire leading to the tank (or its connection to the gauge).
What causes the gas gauge needle to move?
The variations in the amount of fuel in the tank cause the arm to move. This changes the resistance of the tank unit, changing the amount of current at the gauge unit coils, which in turn moves the needle located between the coils.
