What do the F and E on the Leiling fuel gauge represent?

The E and F characters on the Leiling fuel gauge represent the remaining gasoline in the fuel tank. More relevant information is as follows: 1. The fuel gauge displays the fuel level through a float in the fuel tank connected to a metal rod. This principle is similar to the toilet tank in a bathroom. The end of the metal rod connected to the float is linked to a variable resistor via a movable contact point. The position of the float on the fuel surface in the tank changes, which in turn alters the position on the variable resistor via the metal rod. This variable resistor is connected to the car's fuel gauge, and the movement of the fuel gauge pointer is controlled by the amount of current passing through the variable resistor. 2. When the fuel is about to run out, the dashboard will issue a low fuel warning, shaped like a vertical soda can, with the warning symbol in red. Generally, after this warning appears, the car can still travel about 5 kilometers before running out of fuel. Different cars have different settings, so it is essential to find the nearest gas station for refueling after the warning appears.
In my years of driving the Levin, I've learned that the F and E on the fuel gauge stand for Full and Empty respectively. Simply put, F indicates a full tank, while E means the fuel level is critically low and it's time to refuel. Many drivers ignore these indicators until the needle approaches E, but this habit can be harmful—prolonged fuel pump dry-running may cause overheating damage, leading to costly repairs. I recommend maintaining the fuel level between F and E during normal driving, which not only protects the fuel system but also avoids the embarrassment of roadside breakdowns. Additionally, fuel gauge designs account for sensor accuracy, so needle responses may lag, especially during sharp turns or on slopes. Cultivating the habit of regularly checking the gauge and keeping refueling records helps accurately track fuel consumption. Paying attention to these small details can significantly extend your vehicle's lifespan.
I've been driving my Levin to work for several years, and the F and E on the fuel gauge simply indicate the full and empty status of the fuel tank. F is on the right side of the dashboard, meaning there's plenty of fuel; E is on the left, indicating that the fuel is almost empty. I remember one time I was careless and drove until it reached E before refueling, and the engine almost threw a tantrum—the fuel pump overheats when it can't draw fuel. Since then, I've set a rule for myself: when the needle drops below the 1/4 mark, I head to the gas station. This not only saves hassle but also extends the lifespan of car components. The fuel gauge design in the Levin is quite intuitive, but beginners should be aware of its sensitivity—it might give false readings on bumpy roads. I usually check the navigation to see the distribution of nearby gas stations and plan my refueling in advance. After developing this habit, driving has become much less stressful. In short, while the fuel gauge is simple, it's a guardian of driving safety—don't wait until E to take action.
