Abstract
A vehicular fuel tank fuel filler orifice device that is provided with a fuel filler orifice in an upper wall of a vehicular fuel tank that stores ethanol fuel for an engine and a fuel filler guide tube extending from the fuel filler orifice to the interior of the fuel tank. A flame arrestor made of a metal mesh with a larger diameter than that of the fuel filler guide tube is mounted on the fuel filler guide tube. The flame arrestor covers a lower opening of the fuel filler guide tube for allowing a flow of the fuel but preventing the entrance of a flame. Using a flame arrestor, not only prevents a flame from entering a fuel tank from a fuel filler orifice but also smoothly carries out an exchange of fuel and air in the flame arrestor when filling with fuel, thus speeding the filling with fuel.
