Introduction to Fuel Filler Cap
A fuel filler cap is a crucial component of a vehicle’s fuel system. It serves as a protective cover for the fuel tank opening, preventing dirt, dust, water, and other contaminants from entering the tank. Additionally, it helps to maintain the proper pressure within the fuel tank, which is essential for the efficient operation of the vehicle’s fuel system. A well – designed fuel filler cap also plays a role in reducing fuel evaporation, thus contributing to environmental protection and fuel economy. Fuel Filler Cap
