Abstract: A device for feeding fuel from a fuel tank (33) to a multi-fuel engine (12) that uses fuel in which alcohol and gasoline are mixed in an arbitrary ratio. The internal volume of a connecting line (84) provided between a fuel pressure governor (85) and a fuel injection device (50) is a volume equal to or greater than the amount of fuel consumed from startup of the engine until an oxygen sensor (88) reaches a measurement-enabling temperature.

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.

Abstract: Fuel supply equipment for a vehicle includes a fuel filter cover for covering a fuel filter that is disposed outside of a fuel tank. A fuel pressure regulator for keeping fuel supplied to a fuel injection system under predetermined pressure is arranged so that the fuel pressure regulator is located inside the fuel filter cover and is overlapped with the fuel filter cover when a vehicle is viewed from the side. The fuel pressure regulator is connected to an outflow side of the fuel filter via a fuel hose for keeping fuel supplied to a fuel injection system under predetermined pressure. A holder for supporting the fuel pressure regulator is attached to the fuel filter cover before it is attached to a body frame. The resulting configuration enhances the ability to install and maintain a fuel filter provided outside the fuel tank.

Abstract: A vehicular fuel tank fuel filler orifice device that is provided with a fuel filler orifice (15a) in an upper wall (3a) of a vehicular fuel tank (3) that stores ethanol fuel as fuel for an engine and with a fuel filler guide tube (15) extending from the fuel filler orifice (15a) to the interior of the fuel tank (3), wherein the fuel filler guide tube (15) is provided with a flame arrestor (21) and a skirt (27), the flame arrestor (21) covering a lower opening of the fuel filler guide tube (15) and allowing flow of the fuel but preventing the entrance of flame, the skirt (27) extending downward from an outer peripheral part of the flame arrestor (21), and air convection between the fuel tank (3) and the fuel filler guide tube (15) occurring via the flame arrestor (21) being prevented by the skirt (27).

This enables damage to a flame arrestor by a fuel filler gun inserted into a fuel filler orifice to be prevented without using a long fuel filler guide tube.
