See full version: Why Is my Fuel Gauge Stuck on Empty
The most obvious symptom of a stuck fuel gauge is that the fuel indicator does not move, even if you fill several liters of fuel in the fuel tank. If the fuel indicator still does not move, it means that it has been stuck on empty. here
Your fuel gauge plays an important role in indicating that your fuel tank is running out of fuel, and it needs a refill. When you go for a refill, you check your fuel gauge to see whether it is full or not, and how much it has filled. Sometimes, the fuel gauge gets stuck on empty, and you have no idea how much fuel you are left with. Such a situation can be a total loss in case you are on the countryside going for a long drive. Read this oneHOWTO article to know why is my fuel gauge stuck on empty.
Sometimes, the float may have broken down, or it might have separated from its arm, thus causing the fuel gauge to get stuck on empty and not function properly. A malfunctioning resistor may also cause the fuel gauge to read empty and not indicate the correct level of fuel.
A fuel gauge is a component found in the fuel tank of almost every vehicle on the road. It is the component responsible to send signals that operates fuel level gauge of the instrument cluster. It is made up of a float, an arm and a resistor that is designed to change as per the position of the fuel float. The float keeps floating on the top surface of the fuel inside the fuel tank. As the fuel level drops, the float and the arm also shift their position and the resistor moves to control the gauge display inside the vehicle. When the fuel gauge is stuck on empty, you do not get an idea of how much fuel is there in the fuel tank, and you may run out of fuel anytime. [links]

One of the first symptoms of a problem with the fuel gauge sender is a fuel gauge that behaves erratically. A faulty fuel gauge sender may cause the gauge to suddenly change positions, or give an inaccurate reading. The gauge may appear to be at three quarters, and then only a few minutes later will change to half full, or vice versa the gauge may appear to be full, only to have the gauge climb higher a short while later.
Another common symptom of a faulty fuel gauge sender is a gauge that is stuck on empty. If the float somehow breaks or becomes separated from the arm it may cause the fuel gauge to malfunction and become stuck on empty. A faulty resistor can also cause the gauge to read empty. more
The fuel gauge sender is a component that is found in the gas tank of most road going vehicles. The fuel gauge sender, also commonly referred to as the fuel sending unit, is the component responsible for sending the signal that operates the fuel level gauge in the instrument cluster. The fuel sending unit is made up of an arm, float, and a resistor that changes according the position of the float. The sender float is designed to float on the surface of the fuel inside of the tank. As the level drops, the position of the arm and float will shift and move a resistor which controls the display on the gauge. When the fuel sending unit has an issue it can cause the vehicle to experience issues with the fuel gauge, which can put the vehicle at risk of running out of fuel. Usually a bad or failing fuel gauge sender will produce a few symptoms that can alert the driver of a potential issue.
The fuel sending unit is not a routinely serviced component, usually only serviced when it, or the fuel pump fails, however it does play an important role to the proper operation of the vehicle. If you fuel gauge is displaying any of the symptoms, or you suspect that there may be an issue with this unit, have the vehicle inspected by a professional technician, such as one from YourMechanic, to determine if the fuel gage sender should be replaced. here
Is the fuel gauge needle in your vehicle stuck beneath the pin or is it fluctuating from the full mark to the empty mark in a haphazard manner? Read on to know how you can fix your vehicle fuel gauge that is not working properly.
When a vehicle runs out of fuel and faces an empty fuel tank, the needle float drops to the empty indicator, showing the driver that the vehicle is very low on fuel. Some cars show a ‘low fuel’ yellow light to indicate that there is no fuel in the car. If you infer to the working of a fuel gauge, the process is pretty simple, and fail-safe too. However, sometimes, an issue can arise regarding this fuel gauge and it can stop working or work in an erratic manner. more
Call it a “gas gauge” or a “fuel gauge”, this device represents the level of fuel which is present in the fuel tank of any vehicle. It is designed in two parts, viz., an indicator and a sensing unit. What I am going to say here should be a common observation for any uninitiated person. In a car, you must have noticed a unit on the dashboard that indicates the moderation of fuel. There is letter ‘E’ and letter ‘F’ spaced with markings, which means the fuel is either “empty” or “full”. That indication is usually presented by a fuel gauge needle which floats in the unit. This needle is connected to a potentiometer in the sensing unit.
So, after inferring to the working of both these systems, what we learn is that when the fuel tank in the car is completely filled, there is maximum electric current in the unit and the needle points to the letter ‘F’ (indicating full tank). On the other hand, when the fuel tank is empty, the electric current is minimum, making the needle point to the letter ‘E’ (indicating empty tank). here
