A motor vehicle with a pressure vessel system includes at least a first pressure vessel arranged in a first region of the motor vehicle and at least one second pressure vessel arranged in a second region of the motor vehicle having a lower intrusion probability than the first region. Fuel is preferentially removed first primarily from the at least one first pressure vessel. When the lower limit of fuel level or fuel temperature is reached in the at least one first pressure vessel, fuel is removed from the at least one second pressure vessel. If the fuel supply rate from the at least one first pressure vessel is lower than an overall fuel supply rate for an energy converter, fuel is removed from the at least one second pressure vessel to meet the overall fuel supply rate needed by the energy converter.

Provided is a fuel tank made of resin, including: a fuel tank body that is enclosed by a bottom wall, side walls, and an upper wall, the fuel tank body including a first storage portion, a second storage portion, and a coupling portion, the coupling portion communicating an upper portion of the first storage portion and an upper portion of the second storage portion; a pump module disposed in the first storage portion; an open portion formed in the first storage portion; a strut provided in the first storage portion; a separator provided on the strut; a suction portion disposed in the second storage portion; a fuel transfer line that communicates the suction portion to the pump module; a holding portion and a provisional holding portion provided at the separator, the provisional holding portion being configured to removably hold the extra-length portion of the fuel transfer line.

A work vehicle including a drive device (10) having an internal combustion engine (12) for driving a vehicle body (1) has: a first tank (32) that is disposed in front of or behind the drive device, and stores fuel (9) to be supplied to the internal combustion engine; a second tank (34) that is disposed below the drive device so as to be separated from the first tank by a predetermined distance, and stores the fuel to be supplied to the internal combustion engine; a first storage amount detection part (70) that is disposed in the first tank, and detects an amount of the fuel stored in the first tank; and a second storage amount detection part (80) that is disposed in the second tank, and detects an amount of the fuel stored in the second tank.

A fueling system is disclosed for use with a service vehicle with a fuel tank and a main engine, and an auxiliary system. A fuel distribution system can include at least one fuel pump and at least one fuel nozzle. A compound fuel extractor can be configured to engage the main fuel tank of the service vehicle to provide first and second overlapping flow paths out of the main fuel tank. The first overlapping flow path can direct fuel from the main fuel tank to the main engine, and the second overlapping flow path can direct fuel from the main fuel tank to the auxiliary system.

A dual fuel tank system for a machine having a frame and an engine enclosure mounted on a rear portion of the frame includes a pair of support plates located at the rear portion of the frame and welded onto a pair of sides of the frame. Further, the dual fuel system also includes a pair of upper and lower support brackets secured onto each side of the engine enclosure. Furthermore, the dual fuel system also includes a pair of fuel tanks disposed on the pair of sides of the engine enclosure. Each fuel tank is releasably secured onto the support plate and an associated pair of the upper and lower support brackets.

A fuel-conveying system includes: a primary fuel pump, configured to supply fuel to an internal combustion engine of a vehicle, at a fuel pressure; a suction jet pump configured to convey fuel from a first region of a fuel tank of the vehicle to a second region of the fuel tank, the at least one suction jet pump having a nozzle; and a secondary fuel pump, decoupled from the primary fuel pump and configured to: supply, as required, the suction jet pump with a fuel jet, and set, independently of the primary fuel pump, a pressure of the fuel jet before the nozzle of the suction jet pump.

A gas supply system includes: high-pressure tanks having at least different longitudinal lengths; supply pipes each connected to corresponding one of the high-pressure tanks; a supply-side manifold to which the supply pipes are connected; solenoid valves disposed in the respective supply pipes; a first pressure sensor configured to acquire a pressure related to an internal pressure of the high-pressure tanks; a second pressure sensor configured to acquire a pressure at the supply-side manifold; and a control device that controls the solenoid valve corresponding to the high-pressure tank, among the high-pressure tanks, having the largest ratio of the longitudinal length to a short-side width, to open first when a value obtained by subtracting the pressure detected by the second pressure sensor from the pressure detected by the first pressure sensor is larger than a threshold at the time of activation of the gas supply system.

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 gas fuel storage device for a vehicle is provided. The device more easily secures a gas fuel storage capacity and prevents interior marketability of the vehicle from deteriorating.

Methods and systems are provided for providing improving customer satisfaction during a vehicle fuel tank refueling event. A fuel system is configured with a three-way isolation valve and a four port canister. Fuel tank depressurization is expedited by directing fuel tank vapors to a dedicated depressurization port of the canister.
