The fuel tank sealing cap

The cap has no specific purpose, as it performs several critical functions at once. This small element ensures the most correct and efficient operation of the entire fuel system.

It is the gas tank cap and additional vehicle systems that help solve this problem, equalizing the pressure inside the fuel tank at atmospheric level.
