An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.

A fluid port assembly includes a tube configured for positioning with a fluid container to provide access to a fluid contained in the fluid container. The tube includes at least one annular tube recess. The at least one annular tube recess forms a plurality of inner tube surfaces extending circumferentially within the tube. The assembly includes a plug configured for positioning inside the tube to releasably seal the fluid container and contain the fluid within the fluid container. The plug includes at least one annular plug protrusion, and the at least one annular plug protrusion forms a plurality of outer plug surfaces extending circumferentially around the plug. The plurality of inner tube surfaces of the tube interfaces with the plurality of outer plug surfaces of the plug to seal the fluid container.

A tank made of resin provided with a barrier layer, which prevents the barrier layer from rolling up and has improved durability. In a tank made of resin that includes a barrier layer provided on an inner surface of a tank body made of resin, an opening part is provided in the barrier layer, a thick part projecting toward an inside or an outside of the tank body is provided in a resin layer at an outer peripheral part of the opening part, and the barrier layer and a casting flange part at a base of an oil filling port tubular part are molded with the resin of the tank body in a state in which the casting flange part is located at the thick part.

To ease work of transferring a fuel from a fuel supply tank to a fuel tank, a fuel supply guide to be used to supply the fuel by using the fuel supply tank to the fuel tank having a tank body for storing the fuel and a fuel supply port on the upper side of the tank body includes a support member provided on an upper portion of the fuel tank, and a body member projecting from the support member in a direction away from the fuel supply port as the body member extends upward and projecting higher than the fuel supply port. The body member is capable of receiving the fuel supply tank by an upper portion thereof to support the fuel supply tank.

A four-wheel vehicle includes an engine at least a portion of which is located farther forward than a seat, a fuel tank located above the engine and forwardly of the seat, a fuel filler including a fuel filler neck and a filler cap, a breather channel connected to the fuel filler, and an outflow prevention valve in the breather channel to prevent outflow of liquid fuel. The outflow prevention valve is located higher in a side view of the vehicle body than both of a lower end of the fuel tank and an upper end of the engine.

A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.

Fluid containers to evacuate spilled fluid from the interior of an enclosure of the fluid container are disclosed. An example system includes an enclosure and a fluid container within the enclosure. The fluid container includes a fluid capture area at a top of the fluid container and a channel at a side of the fluid container. The fluid capture area directs the fluid to the channel, and the channel directs the fluid from an interior of the enclosure to an exterior of the enclosure

A fuel tank includes a tank main body and a fuel filler neck. A breather hole is provided in an inner surface of the fuel filler neck. A connecting pipe opens to the inside of the fuel filler neck though the breather hole and extends from the fuel filler neck in the radial direction. The inside of the fuel filler neck includes a first vapor-liquid separation chamber therein that is partitioned from the tank main body and connected to the breather hole. Liquid fuel entering the breather channel is reduced.

A fuel tank structure for a saddle-ride vehicle for discharging fuel leaking out from a filler neck between a cover member and a fuel tank. The fuel tank structure includes a filler neck having a collar portion projecting upwardly from an upper surface of a fuel tank with a tank cap to seal the filler neck. A tank cover includes a cover opening portion into which the collar portion is inserted for covering the circumference of the filler neck. The tank cap has an extending wall portion for surrounding the outside of the collar portion and extending to a position below the cover opening portion so that fuel leaking from the filler neck is discharged through a clearance between the fuel tank and the tank cover.

The invention relates to a closure system on a fuel tank (2) of thermoplastics with barrier properties for hydrocarbons. The closure system comprises at least one orifice (4), with a closure cap (5) which closes the orifice (4) in a sealing manner and which cooperates in a form-fitting manner with closure means provided at the circumference of the orifice (4) and encloses at least one first sealing means between it and a tank wall (3). The closure system (1) according to the invention is distinguished in that the tank wall is sealed in the region of the orifice (4) with at least one second sealing means, which covers and/or shields a part of the tank wall surfaces exposed to hydrocarbons.
