An evaporated fuel processing device that includes a pump configured to supply purge gas, which includes evaporated fuel in a fuel tank, to an intake passage of an engine through a purge passage; a controller configured to control the pump; and a detecting unit configured to acquire a gas amount introduced to the intake passage while the pump is being driven in a stable state where an air amount introduced from open air to the intake passage is stable, and configured to detect, by using change in the acquired gas amount, a state where the purge gas is unable to be normally supplied from the purge passage to the intake passage.

Methods and systems are provided for reducing an amount of fuel vapors that are routed to a fuel vapor storage canister during a refueling event, in response to an indication that a fuel dispenser that is dispensing fuel to a fuel tank is underperforming. In one example, a method comprises increasing a pressure in the fuel tank responsive to an indication that the fuel dispenser is dispensing fuel at a first rate that is at least a threshold amount below a second rate, without changing the first rate at which the fuel dispenser is dispensing the fuel. In this way, fuel vapor recirculation may be improved and an amount of fuel vapors routed to the canister reduced, which may thus reduce opportunities for release of undesired evaporative emissions to atmosphere.

A vehicle structure includes a fuel tank configured to store a fuel supplied to an internal-combustion engine of a vehicle and a battery configured to store an electric power supplied to an electric motor of the vehicle to drive the vehicle. A gravity center of the battery is lower than a gravity center of the fuel tank, and at least a part of the fuel tank overlaps with the battery in a top plan view of the vehicle.

A fuel tank system is provided with at least two separate tank bodies, each with a respective tank body interior, and a connecting element connecting the tank bodies for fluid communication. The tank bodies are connected to each other by means of a connector and are fabricated from a plastic material. The fuel tank system is formed with receiving means (5) for arrangement on a frame of a vehicle, such as a motorcycle, having a driver's saddle. The fuel tank system includes a distributor element with a fuel filling opening; the distributor element is connected in a fluid-conducting manner to the tank bodies via at least one fluid-conducting connector.

A fuel pump module includes a fuel pump, a housing, a filter, a bracket, a lid, a fuel passage, and a pressure regulating valve. The fuel pump supplies a fuel in a fuel tank that defines an opening to an outside of the fuel tank. The housing has a cylindrical shape and supports the fuel pump. The bracket connects the filter to the housing. The lid covers the opening and defines a discharge port through which the fuel is supplied to the outside. The fuel passage connects the fuel pump to the discharge port. The pressure regulating valve has a gravity center inside a space defined by a first virtual cylindrical surface including the housing. A minimum circumscribed circle of both the housing and the filter is smaller than the opening.

A method and apparatus for modifying an existing style fuel tank to add a fuel pump and a baffle assembly in the tank comprises removing an existing fuel sending unit from a sending unit opening and cutting an access hole in the top of the tank. Fuel supply and return lines, and electrical connections for the fuel pump are routed through a replacement cap for covering the sending unit opening and not up through the hole created for insertion of the pump and baffle assembly. The baffle assembly includes a cup for holding fuel around and over the fuel pickup connected to the fuel pump. The cup may be formed from a compressible material to allow it to be compressed before insertion into the tank through the access opening or it may be assembled inside of the tank from segments inserted through the access opening.

A siphoning assembly for a fuel supply system comprises an adaptor body with a pressurized fuel inlet, a suction inlet and an outlet and an outlet passageway connecting the pressurized fuel inlet and the suction inlet to the outlet. A venturi nozzle extends in-line with the pressurized fuel inlet and opens into a suction chamber to create a pressure drop for pulling in fuel from the suction inlet which also opens into the suction chamber. The outlet passageway forming a liquid trap between the suction chamber and the outlet. The siphoning assembly may include a pressure relief valve connected to the pressurized fuel inlet formed as a bypass line of the pressurized fuel supply line. The siphoning assembly may be used in conjunction with an apparatus for modifying a fuel tank to add a fuel pump and baffle assembly which may include one-way check valves.

A fuel tank cover attachment assembly includes a fuel pump cover and an attachment ring. The fuel pump cover has an attachment flange configured to overlay a surface surrounding a fuel tank opening such that with the fuel pump cover overlaying the surface, the fuel tank opening is covered. The attachment ring is dimensioned to cover the attachment flange of the fuel pump cover and attach to attachment features protruding from the surface. The attachment ring has a first flange member and a second flange member. The first flange member is fixedly attached to the attachment ring and extends upwardly therefrom. The second flange member is removably attached to the attachment ring and extending upwardly therefrom.

A work vehicle including a tank (31,131) formed so as to extend from a rear part of a vehicle body toward a center, wherein the tank includes: a first storage tank (32) located on the rear side of the vehicle body, and stores stored fluid (9); a second storage tank (34) located on a side close to the center in the front-rear direction of the vehicle body, and stores the fluid; a partition part (36) that separates the first storage tank and the second storage tank; a discharge member (49) that has a discharge opening (49a) extending and opened inside the second storage tank, and discharges, from the second storage tank, the fluid stored in the second storage tank; and a hollow tube member (60) that has a first end communicated with the first storage tank through the partition part so as to enable the stored fluid to flow, and a second end having a hollow tube opening (62) extending and opened toward the center of the vehicle body inside the second storage tank, wherein the hollow tube opening of the hollow tube member is located on the central side of the vehicle body with respect to the discharge opening of the discharge member.

In at least some implementations, a wire includes a core formed from an electrically conductive material and having an outer surface, and a polymeric insulator surrounding the core. The insulator has a resistivity of between 10.sup.5 and 10.sup.9 ohms/square, and the insulator has an inner surface engaged with the core. In at least some implementations, the core is formed from metal and has a conductivity of at least 1106 m. The insulator may include a base material and a conductive material in the base material, wherein the conductive material has a conductivity between 10.sup.5 and 10.sup.6 ohms/square. The insulator may have an outer surface that defines an outer surface of the wire and/or the insulator may have an inner surface engaged with the core.
