A fuel head assembly for a fuel tank has a fuel head body, an inlet connector, an inlet tube, an overflow tube, and a fuel level sensor. An upper end of the fuel body has an inlet port, a sensor port, an overflow port, and a vent port. The lower end of the fuel head body is connectable to the fuel tank. The inlet connector is connected to an upstream end of the inlet port. The inlet tube is connected to a downstream end of the inlet port. The inlet tube extends into the fuel tank. The overflow tube is connected to the overflow port. The fuel level sensor is positioned in the fuel sensor port and has a portion extending into the fuel tank

A urea filler neck for preventing a urea overflow includes a filler housing forming a urea path in which urea flows to a urea tank. An injection gun guide is provided in the filler housing. An end of an injection gun is fixed by the injection gun guide to limit an insertion position of the injection gun inserted into an inlet of the filler housing. An injection gun guide flooding phenomenon is generated, in which urea flowing backward from the urea tank rises to block an air flow in the filler housing being generated in the injection gun guide. A filler housing pressure increasing phenomenon is generated, in which a pressure in the filler housing is increased due to blocking of the air flow by the injection gun guide flooding phenomenon being generated in the injection gun guide.

Disclosed is a system and method for delivering fuel to a plurality of vehicles. The system comprises a fuel source, a pump operable to draw fuel from the fuel source and a distribution manifold having a plurality of outlets. The system further comprises a plurality of fuel lines extending from the distribution manifold and a plurality of valve assemblies, each located in a tank of one of the plurality of vehicles each of the valve assembly being operable to independently shut off flow of fuel therethrough when the tank is filled to a predetermined level. The method comprises pumping the fuel supply from the fuel source to the distribution manifold, connecting a plurality of fuel lines to the distribution manifold and a valve assembly in each of a plurality of trucks in connection with one of the fuel lines.

An automatic fill system includes a tank, a transfer hose, and a valve assembly. The valve assembly has a first end having an outlet orifice configured to be received within the tank. The valve assembly also includes a second end configured to be connected in fluid communication with the transfer hose with the second end having an inlet orifice. The valve assembly also includes at least one fluid passageway between the inlet orifice and the outlet orifice, and a check valve coupled to a spring and a seal. The seal is configured to be slidably moveable within a piston chamber. The valve assembly further includes a heating element located within a heating element chamber and configured to heat the valve assembly. Finally, the valve assembly includes a jet level sensor with a sensor inlet and a sensor outlet. The jet level sensor is in fluid communication with the piston chamber.

A mobile fluid transfer system. The system includes a fluid evacuation system, a fluid refill system, a sensing system and a control system. The fluid evacuation system comprises a first fluid storage container. The fluid refill system comprises a second fluid storage container. The sensing system is coupled to the fluid evacuation system and the fluid refill system. The control system is coupled to the sensing system, the fluid evacuation system and the fluid refill system. The control system is configured to determine an amount of a first fluid in the first fluid storage container based on a first signal from the sensing system, and determine an amount of a second fluid in the second fluid storage container based on a second signal from the sensing system.

A routing system for an agricultural sprayer includes a support configured to operably couple with the sprayer. An adaptor is configured to transfer a flow therethrough. The adaptor is at least partially positioned within an envelope defined between a wheel assembly and laterally offset components of the sprayer. A conduit has a first section operably coupled with a first portion of the adaptor and a second section operably coupled with an opposing second portion of the adaptor. The first section and the second section of the conduit are configured to transfer the flow therethrough such that the flow is serially transferred through each of the first section of the conduit, the adaptor, and the second section of the conduit.

A system for filling a tank for a firefighting helicopter with water without ground personnel, comprising a pilot controlled valve assembly to selectively permit water to flow into the refill tank upon the receipt of a communication transmitted by a communication device within the helicopter. The pilot controlled valve assembly can include a supply valve configured to move between at least a closed state and an open state, a controller configured to control the supply valve, and a receiver configured to send a signal to a controller to cause the controller to at least open the supply valve upon receipt by the receiver of a communication meeting one or more predetermined criteria. The water tank can be filled from a water source, including a municipal water source, when the supply valve is open to provide a more efficient, semi-autonomous refill tank system greatly improves costly and time-consuming manually refill systems.
