Can Overfilling the Fuel Tank Damage the Fuel Gauge?
1 Answers
Overfilling the fuel tank can damage the fuel gauge. Filling the tank too full may cause the fuel float and sensor to malfunction, leading to inaccurate fuel gauge readings. The fuel gauge consists of a voltage regulator, fuel indicator, and fuel level sensor. The low fuel warning system alerts the driver when the fuel level drops below a specified threshold, prompting immediate attention. Precautions for using the fuel gauge include: 1. Refuel before the warning light comes on, as insufficient fuel can impair the fuel pump's operation and shorten its lifespan; 2. Expect minor deviations in readings, such as when replacing the battery or fuel filter, where the gauge may show a lower level upon restarting due to pressure release in the tank, which is normal.
