The material provides a fixed seal between plug and tank. The dimensions are matched to a diameter of twenty by twenty six millimetres. The ring is used during maintenance or when replacing the existing seal. The design follows the original factory specifications. The ring supports reliable operation of the fuel system and limits loss of petrol during use and when draining the tank for service work.
