Provided is a fuel tank of a work vehicle in which fuel can be easily sucked into an engine. The fuel tank includes: a drain port which is open to an outside on a side surface and through which fuel is discharged to the outside; a suction port which is open to the outside on a side surface and has a center positioned lower than a center of the drain port and through which the fuel is sucked by an engine; and a first recess which is formed to be recessed downward with respect to a bottom surface and communicates with the drain port.

A tool for draining and refilling a vehicle tank for cryogenic fuel, wherein the tool when in position for use has a vertical direction and includes a heat exchanger and a cooling tank, the cooling tank having an upper portion and a lower portion as viewed in the vertical direction of the tool and including a fuel outlet having at least one outlet valve, the fuel outlet being connected to a first fuel conduit and second fuel conduit via the at least one outlet valve, wherein the first fuel conduit includes an arrangement for connecting the first fuel conduit to an inlet on the heat exchanger, and wherein the second fuel conduit includes an arrangement for connecting the second fuel conduit to an inlet on a vehicle tank, the cooling tank further including an inlet, the inlet being connected to a fuel inlet conduit via a check valve and the fuel inlet conduit including an arrangement for connecting the inlet to an outlet from the heat exchanger, or to an outlet from a vehicle tank, and the outlet of the heat exchanger including an arrangement for connecting to an inlet on a vehicle tank, and a system and method for draining and refilling a vehicle tank.

The present invention relates to a method for controlling a fuel tank arrangement (100) connected to a prime mover (101) for propulsion of a vehicle. More particularly, the fuel tank arrangement (100) comprises a first (102) and a second (104) fuel tank connected to the prime mover of the vehicle.

Power machine fuel tanks include a plug receptacle and a cover for the plug receptacle which seals the plug receptacle from an interior of the fuel tank. A receptacle insert positioned within the plug receptacle allows a fuel plug to be removably secured to the fuel tank. The cover prevents leakage from inside the fuel tank through the plug receptacle, regardless of whether the plug is secured within the receptacle insert, unless the cover has been removed from a sealing position.

A saddle-ride type vehicle for enabling the placement of canisters with a required absorption-chamber capacity in a compact manner. The saddle-ride type vehicle includes a head pipe supporting a steering shaft connecting with a handlebar; a vehicle-body frame connecting with the head pipe; a fuel tank placed to the rear of the head pipe and supported on an upper portion of the vehicle-body frame; and a pair of canisters for absorbing evaporated fuel introduced from the fuel tank. The canisters are vertically placed under one side portion of the fuel tank in a position along the vehicle-longitudinal direction.

An opening-closing apparatus for a fuel tank comprises a fuel passage-forming portion configured to form a fuel passage that is arranged to introduce a supplied liquid fuel to the fuel tank; an insertion-side opening-closing mechanism configured to open and close the fuel passage; a tank-side opening-closing mechanism located on a fuel tank side of the insertion-side opening-closing mechanism and configured to open and close the fuel passage; a liquid discharge path configured to allow for communication of a portion of the fuel passage between the insertion-side opening-closing mechanism and the tank-side opening-closing mechanism to the outside of the opening-closing apparatus; and an open-close valve configured to open and close the liquid discharge path and to be opened toward the outside. This configuration of the opening-closing apparatus for the fuel tank reduces dust and the like invaded from the outside into the fuel passage which a liquid fuel passes through.

It is intended to enable a saddled vehicle, including an internal combustion engine supported by a lower part of a vehicle body frame, a fuel tank supported by an upper part of the vehicle body frame, a canister including an external air introducing pipe for introducing an external air, and a vehicle body cover covering the vehicle body frame, the internal combustion engine and the fuel tank, to efficiently discharge steam, released from the external air introducing pipe of the canister, to the outside of the vehicle. An external air introducing tubular pathway extends inside the vehicle body cover while continuing at one end thereof to the external air introducing pipe of the canister. An other end-side opened portion of the external air introducing tubular pathway is opened to the outside of the vehicle body cover while penetrating a through hole formed in the vehicle body cover.

An active drain liquid trap configured for use with a fuel tank system and constructed in accordance to one example of the present disclosure includes a trap body, a float and a pilot. The trap body defines a first inlet, a second inlet and an outlet. The first inlet is fluidly connected to a fuel pump. The second inlet is fluidly connected to a vapor line. The float is rotatably mounted about a float pivot. The pilot moves between an open and closed position. Rotation of the float causes the pilot to be urged into an open position and fluid to be drained from the trap body through the outlet.

One embodiment of a molded fuel tank includes a fuel tank molded as one piece of rotationally molded cross-linked polyethylene material. One embodiment may include molding a fuel tank wall as a single layer of material with a metal component fastening structure positioned within the single layer fuel tank wall as it is molded.

An aircraft fuel storage system is disclosed including a fuel tank comprising a chamber for storing fuel, the chamber comprising a first side, a second side, and a base connecting the first side to the second side; a collector; and a first conduit and a second conduit, each of the first and second conduits fluidically coupling the chamber to the collector so that fuel is freely passable from the chamber to the collector via the respective first and second conduits. The first and second conduits open into the chamber at respective first and second conduit openings, the first conduit opening is nearer to the first side than the second conduit opening is to the first side, and the second conduit includes a second conduit lock portion that is nearer to the first side than the second conduit opening is to the first side. Also disclosed is an aircraft including the aircraft fuel storage system.
