A fuel tank system constructed in accordance to one example of the present disclosure includes a fuel tank and an evaporative emissions control system. The evaporative emissions control system is configured to recapture and recycle emitted fuel vapor. The evaporative emissions control system includes a liquid trap, a first device, a second device, a control module and a G-sensor. The first device is configured to selectively open and close a first vent. The second device is configured to selectively open and close a second vent. The control module regulates operation of the first and second devices to provide over-pressure and vacuum relief for the fuel tank. The G-sensor provides a signal to the control module based on a measured acceleration.

An evaporative emissions control system includes a first vent valve configured to selectively open and close a first vent, a second vent valve configured to selectively open and close a second vent, a fuel level sensor configured to sense a fuel level in the fuel tank, a pressure sensor configured to sense a pressure in the fuel tank, an accelerometer configured to measure an acceleration of the vehicle, and a controller configured to regulate operation of the first and second vent valves to provide pressure relief for the fuel tank. The controller is programmed to determine if a refueling event is occurring based one signals indicating the fuel level is increasing, the pressure in the fuel tank is increasing, and the vehicle is not moving, and open at least one of the first and second vent valves based on determining the refueling event is occurring.

A fixture for piping includes a fitting. The fitting includes a base, and a locking tab. The locking tab has an end fixed onto the base, and one or more folding sections. The locking tab is formed as a folding configuration folded twice or more, and is further formed so as to be inclinable by elastic deformation about the end and the one or more folding sections serving as a fulcrum, respectively, thereby being locked up with a hole in a vehicle body.

A work vehicle includes a front and a rear opposite to the front in a front-rear direction of the work vehicle, and a lateral direction perpendicular to the front-rear direction. The work vehicle further includes an engine, a hood, a fuel tank, a fuel supply path, a separator, and a front protector. The hood is to cover the engine. The fuel tank is to store fuel. The fuel stored in the fuel tank is to be supplied to the engine via the fuel supply path. The separator is provided in the fuel supply path to remove water in the fuel flowing through the fuel supply path. The separator includes a protruding portion protruding from the hood in the lateral direction. The front protector is provided at a front side with respect to the protruding portion of the separator to protect a front portion of the protruding portion.

A compartment wall structure defines a fuel filler compartment that includes a tube receiving opening and a vent opening. A fuel receiving end of a fuel filler tube is located at the tube receiving opening of the fuel filler compartment. A fuel tank attachment end thereof is located outside the fuel filler compartment and is spaced apart from the compartment wall structure. An air vent structure is in fluid communication with the vent opening. The air vent structure defines a chamber opening connected via a vent line to a fuel vapor filter canister. Vapor from the fuel filler compartment is vented to the fuel vapor filter canister through the chamber opening. The air vent structure has a screen at the chamber opening to prevent entry of objects, such as, for example, insects and/or debris through the chamber opening.

The invention relates to a liquid/vapor separator (1) for a fuel tank for motor vehicles, comprising a housing (2) having a droplet collecting space (9) for fuel in vapor form. The housing (2) is provided with a connection cross section (4) which, in the installed position, opens into a space surrounded by a filler pipe of the motor vehicle. The liquid/vapor separator (1) comprises at least one first connection (6) for a refueling vent line of the fuel tank, said connection opening into the droplet collecting space (9), a second connection for a service vent line of the fuel tank, and a third connection (8) for a vent line leading to a fuel vapor filter. The liquid/vapor separator (1) according to the invention furthermore comprises at least one valve, which closes at least a service vent path (12) from the second connection to the fuel vapor filter during refueling of the motor vehicle, wherein the service vent path (12) is routed as a channel bypassing the droplet collecting space (9) into the connection cross section (4) of the housing (2).

To provide a fuel line joint capable of improving resistance to an external force in a joint configured to store a liquid fuel. A fuel line joint is equipped with an integrally formed main body portion that has a storage region configured to store a liquid fuel in a lower part thereof and has an opening portion above the storage region of the liquid fuel; a lid that is formed separately from the main body portion, is attached to the main body portion so as to close the opening portion of the main body portion, and is not connected to members other than the main body portion; and a plurality of mounting portions that is formed integrally with the main body portion and mounted to each of a plurality of pipes forming a fuel line.

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.
