Regularly checking your fuel gauge of your car is important especially if you plan to go on a long trip or to an unfamiliar place. This is to ensure that you will have enough for your trip and not get caught unaware in a deserted place, or a few miles from the next gasoline station and terrible far from your destination. There are two main parts that composes the fuel gauge's ability to do its function, and one of these two parts is the fuel sending unit.

The fuel sending unit is located in your vehicle's fuel tank and is used to measure the level of fuel in the tank. The fuel sending unit consists of a float and is connected to a metal rod which is mounted to an electrical device called a variable resistor that can resist the flow of electricity. This device has a strip of resistive material connected on one side to the ground and a wiper slides along this to conduct current from the gauge to the resistor. The distance of the wiper is to the strip determines the amount of resistance. The resistance is large if the wiper is at the end of the strip far away from the ground. And there is only a small resistance if the wiper is close to the grounded side of the strip. And if this is the case then there is a large amount of current that passes thru the sending unit to the fuel gauge and the float is near the top of the tank. The float sinks if the level of the tank drops and the resistance increases, the wiper moves and the amount of current sent back to the gauge decreases.

The float drops when the fuel drops below a certain level but sometimes the float can drop to the bottom even if there is enough fuel but the reading sent maybe inaccurate, showing an empty fuel tank when it isn't so. Also, the shape of the tank affects the accuracy and veracity of the measurement because the float can drop halfway even when there is enough fuel.

If your sending unit is giving you inaccurate information, you can have your mechanic check it.
