A system, for use with a reservoir, for delivering an additive to a fuel tank is provided. The system comprises: a controller, the controller including a processor, a memory, the memory having housed therein instructions for controlling the processor, a display and a keypad; a temperature sensor, the temperature sensor in electronic communication with the controller; and a fluid delivery system, the fluid delivery system comprising: a pump, the pump for fluid communication with the reservoir and in electronic communication with the controller; a flow sensor, the flow sensor in fluid communication with the pump and in electronic communication with the controller; at least one valve, the valve in electronic communication with the controller and in fluid communication with the flow sensor; and at least one outlet, the outlet in fluid communication with the valve. A method of remotely adding an additive to a fuel tank is also provided.

A fuel tank device of a vehicle includes a fuel supply pipe, a first fuel tank, a second fuel tank, and a resistance portion. The fuel supply pipe includes a main pipe, and a first branch pipe and a second branch pipe that branch from the main pipe. The first fuel tank is connected to the first branch pipe, the second fuel tank is connected to the second branch pipe, and the resistance portion is provided in the main pipe and is configured to impart resistance to liquid fuel flowing in the main pipe.

The invention relates to a fuel tank (10) having at least two layers (12) stacked one on top of the other, wherein the layers (12) each have a plurality of single tanks (14) lined together. The invention further relates to a vehicle (100) having the fuel tank (10).

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 trailer that includes a tank with an enclosed interior space configured to hold fluid. The trailer can include a chassis that supports the tank and wheels for moving to desired locations. The tank can include planar opposing sides with rounded corners. One or more baffles can be located within the interior space. The baffles restrict the movement of the fluid within the interior space while the trailer is being moved between locations. This restriction reduces the forces that the moving fluid exerts on the tank which could cause damage to the tank that could result in leaks and failure.

Fuel isolation systems, apparatuses and methods are described. In some embodiments, a system comprises a connector coupled inline with a fuel line on a cold side of the fuel line, a valve coupled to the connector, a fluid feed line coupled to a fluid source and to the valve. In the event of an engine fire condition, a control unit outputs signaling to stop pumping the fuel and to operate the valve to introduce fluid from the fluid source into the fuel line. The introduced fluid provides a siphon break in the fuel line such that the only fuel that can pass the firewall is the remaining fuel in the fuel line downstream of the connector and the introduced fluid.

Systems and methods for balancing levels of liquid fuel among multiple vehicle-mounted fuel tanks utilize at least one control valve that is configured to admit pressurized gas into a first fuel tank while a second fuel tank is ventilated, responsive to detection of a difference of liquid fuel levels within the first and second fuel tanks. Admission of pressurized gas into one fuel tank and ventilation of another fuel tank creates a pressure imbalance that causes liquid fuel to flow through a balancing line connecting the fuel tanks. Balancing may be performed in a bidirectional manner.

Methods and systems are provided for increase a rate at which a saddle fuel tank is depressurized responsive to a request for refueling. In one example, a method may include, responsive to the request for refueling, depressurizing a primary side of the saddle fuel tank to a secondary side of the saddle fuel tank, and commanding open a refueling lock coupled to the primary side to allow fuel to be delivered to the primary side when pressure in the primary side drops below a threshold pressure. In this way, the secondary fuel tank may be maintained at atmospheric pressure prior to the request for refueling, which may increase the rate of depressurization of the saddle fuel tank responsive to the request.
