During driving, especially on unpaved roads, the fuel tank will not only be impacted by the ground, but also shake with the bumps of vehicles. After a long time, the fuel tank will be deformed, and in severe cases, the fuel tank will leak oil, which will affect the driving safety. Therefore, it is necessary to install the fuel tank guard.
