Why does the fuel gauge show only one bar after a full tank?

[Pluto]

If the fuel gauge shows only one bar after a full tank, it could be due to an issue with the fuel gauge itself or a problem with the fuel level sensor (fuel float). It is recommended that the owner take the vehicle to a repair shop for inspection to determine the exact cause. Generally, for fuel-injected vehicles, it is advisable not to wait until the fuel is nearly depleted before refueling. This is mainly because the fuel pump in fuel-injected vehicles is installed inside the fuel tank and relies on gasoline for cooling. If the fuel is almost depleted, it can lead to insufficient cooling of the fuel pump, potentially causing it to overheat and fail. Additionally, running out of fuel can result in insufficient fuel supply, leading to engine stalling. Notes on refueling: 1. For fuel-injected vehicles, avoid waiting until the fuel is completely exhausted before refueling, as this can cause the fuel pump to overheat and malfunction; 2. Do not fill the tank to full capacity in one go, as this increases the vehicle's weight and fuel consumption; 3. Whenever possible, use high-quality fuel, which promotes complete combustion in the cylinders and can extend the engine's lifespan.
