Title: Reserve fuel tank for moped, scooter etc - is cylindrical downward extension of main filler cap with lower valve
IPC: B62J35/00
Filed: 1973-05-10
Abstract: The reserve fuel tank is integral with the lower side of the filler cap and consists of a cylinder (8) with a valve at the lower end. The valve can be opened or shut by turning a knob (14) which is located at the top end of the tank.
