Abstract
Abstract A fuel tank for motorcycles and other like vehicles. The fuel tank has a filling up indicating device comprising a float which can float on fuel stored in the tank; a stem which is attached to said float, and extends upwards to have an indicator at the top; and a support member which is installed inside a fuel supply port to vertically slide and support said stem. The configuration provides for simple information that the tank is being topped up when refuelling, thus preventing fuel from overflowing.
