Why does the fuel gauge needle not rise after filling up the tank?
1 Answers
When the fuel gauge needle does not rise after filling up the tank, it is usually due to a damaged fuel level sensor (fuel float). It is recommended to take the vehicle to a repair shop and connect the two wires of the fuel float. If the fuel gauge needle reaches the top, it indicates a damaged fuel float. If the needle still does not move, check the wiring and the instrument panel. If the needle does not move immediately after filling up the tank, it may be because the fuel float is pushed to the top of the tank by the buoyancy of the fuel. Below is an extended introduction: 1. Automobile fuel tanks can be categorized by material: steel tanks and aluminum alloy tanks. With the development of various new materials, the rust prevention issue of steel fuel tanks has become a major concern for tank quality, especially in today's environmentally conscious era. 2. In the heavy-duty truck sector: During the promotion of National IV and V emission standard vehicles, the quality of fuel in China has become a key issue affecting the adoption of new models. Among these, the quality of the fuel tank, which holds the fuel, is particularly important. Aluminum alloy tanks not only meet strength requirements but also offer significant advantages in corrosion resistance compared to steel and other new materials. They have become the preferred choice for large buses and heavy-duty trucks, which consume large amounts of fuel and require high fuel quality. Automobile fuel tanks can also be categorized by function: standard tanks and heated tanks.
