In order to reduce the amount of dust in the air entering the tank, the air vents should be fitted with air filters. The fuel tank must have a 1.5mm vent and an oil return connection to facilitate the separation of air and other gases from the fuel without pressure in the fuel tank, and the vent must be able to avoid the ingress of dirt and water. The vent can be integrated with the fuel filler, and the fuel filler must be equipped with a filter with a filtration accuracy of 60um to prevent dirt from entering the fuel tank when filling fuel   Our products are according to the standard of OEM to manufacture.
