The first circuit (11) and the second circuit (21) are configured to be in fluid communication: —in a filling phase, when fuel gas flows in the first and second filling pipes (14, 24) from the filling device (50) towards the first and second tanks (12, 22); —and in a working phase, when fuel gas flows in the first and second supply lines (13, 23) from the first and second tanks (12, 22).

A method grants an enablement of refueling of a motor vehicle. The method includes the steps: i) detecting a tank temperature value which is indicative of the present temperature of at least one pressure vessel of the motor vehicle and/or of the fuel stored in the at least one pressure vessel; ii) determining a temperature difference value which is indicative of the present difference between the tank temperature value and an ambient temperature value which is indicative of the ambient temperature; and iii) releasing a tank flap, wherein the tank flap is released by the motor vehicle for the purposes of refueling only if the temperature difference value is lower than a temperature difference threshold value.

Methods, systems, and apparatus for monitoring a cylinder. The system includes a plurality of sensors connected to the cylinder and configured to detect deformation data associated with the cylinder. The system includes a controller communicatively coupled to the plurality of sensors. The controller is configured to determine a damage value based on the detected deformation data when the cylinder endures impact damage. The controller is configured to communicate a notification when the damage value exceeds an impact damage threshold. The system includes a filling controller communicatively coupled to the plurality of sensors. The filling controller is configured to control a valve for filling the cylinder with a fluid. The filling controller is configured to detect damage to the cylinder above a specified threshold as the cylinder is filled with the fluid. The filling controller is configured to automatically perform a safety action when the damage to the cylinder is detected.

A UTV spare fuel tank is provided. The spare fuel tank includes a main body and a lid coupled to the main body. The main body may include a storage compartment and a fueling compartment accessible by opening the lid. The spare fuel tank include a fuel reservoir formed between an outer wall and an inner wall of the main body. The outer wall forms the outer dimension of the main body and the inner wall forms the storage compartment and the fueling compartment. The spare fuel tank may also include brackets and lift members coupled to the main body and extending below a bottom surface of the main body to lift the main body off of a storage shelf to form a gap between the bottom surface and the storage shelf.

A vehicle equipped with a high pressure tank has mounted in the interior of a vehicle body a high pressure tank having a resin liner and a reinforced layer, the vehicle comprising a tank chamber, a filling port, a concave portion in which the filling port and a ventilation port are disposed, a fuel lid capable of opening and closing an opening of the concave portion, and a ventilation passage that allows communication between the ventilation port and the tank chamber. When the fuel lid is opened, the ventilation port is opened to the exterior of the vehicle body, whereas when the fuel lid is closed, the ventilation port is covered by the fuel lid in a state in which the ventilation port is allowed to communicate with the exterior of the vehicle body.

A fill limit vent valve for a fuel system includes a housing assembly, an outlet port and a flow dam. The housing assembly has a main housing including a cylindrical body and an upper housing portion. The upper housing portion has a lower wall that defines an orifice and an outer cylindrical wall that defines an upper housing chamber. The outlet port is formed on the main housing and fluidly communicates fuel vapor out of the fill limit valve. The orifice is offset from a centerpoint of the lower wall in a direction away from the outlet port. The flow dam extends from the lower wall into the upper housing chamber and connects on opposite ends to the outer cylindrical wall. The flow dam and upper housing chamber cooperating to form a liquid trap that mitigates the possibility of liquid fuel from reaching the outlet port from the orifice.

A cap includes a bottomed first cover portion, and a second cover portion provided on a receiving opening side of the first cover portion. The second cover portion includes an outside cover that covers a contact portion of a receptacle. The contact portion comes into contact with a distal end of a supply nozzle when the supply nozzle is connected with the receptacle. The outside cover has a tapered shape such that an outer diameter of the outside cover is decreased towards the first cover portion from one end of the cap where the receiving opening is provided. The outside cover has an internal dimension that allows the outside cover to be separated from an outer peripheral portion of the receptacle when the cap is attached to the receptacle.
