A service device for a pressure vessel system of a motor vehicle includes a service-device-side refueling coupling part which is connectable to a motor-vehicle-side refueling coupling part of the motor vehicle and a controller for activating the pressure vessel system. A method for the service of the pressure vessel system includes producing a connection between the service device and the pressure vessel system and activating the pressure vessel system by the service device.

A hydrocarbon dispensation line pressure sensor adapted to work without requirement of a separate closed valve. The system closes the dispensation line upstream via an isolation valve. The pressure can be sensed from the dispensation line through the valve to provide dispensation line pressure. A channel in fluid communication with the dispensation line may be provided to allow pressure measurement apart from the main dispensation line. Further, a method for measuring the pressure drop profile of a dispensation line and various methods to determine the pressure loss due to leaks in dispensation line.

In some embodiments, an apparatus includes a housing and a mount. The housing includes a cover portion and a base portion. The cover portion and the base portion define an interior. The housing defines an opening via which the interior can be accessed from a region external to the housing. The mount is coupled to the base portion and configured to maintain a position of a fillable component within the interior of the housing such that an elastomeric membrane of the fillable component is aligned with the opening defined by the housing and a reservoir of the fillable component is accessible by a needle via the opening and the elastomeric membrane.

A method and apparatus are provided for controlling a fuel delivery system to limit acidic corrosion. An exemplary control system includes a controller, at least one monitor, an output, and a remediation system. The monitor of the control system may collect and analyze data indicative of a corrosive environment in the fuel delivery system. The output of the control system may automatically warn an operator of the fueling station of the corrosive environment so that the operator can take preventative or corrective action. The remediation system of the control system may take at least one corrective action to remediate the corrosive environment in the fuel delivery system.

A dispensing unit having a circulation system for circulating a fluid in the dispensing unit is provided. The circulation system comprises, a circulation circuit, and a mechanism configured to circulate the fluid in the circulation circuit. By circulating the fluid, the fluid is counteracted from crystallizing. A method for circulating a fluid in a dispensing unit is also provided.

This disclosure presents a deployable spill containment system and method. In one embodiment, the spill containment device forms a shallow container covering a large area. The coverage area and depth may vary. The spill containment device may have deformable walls that allow vehicles to drive over and into the protection area during deployment. Furthermore, the spill containment device may be rolled, folded, or both, for storage and transportation, such as fitting in a bed of a pickup truck. The spill containment system includes replaceable components for easy repair, exchange, and modification when needed.

A system, apparatus and method for on-demand fueling of vehicles with a mobile, motorized handcart including a cart body coupled with a fuel tank, a plurality of wheels operatively connected to the cart body, the wheels operable with a motorized traction system, a steering handle operatively connected to the cart body and including controls for controlling the motorized traction system, a coupling system for securely coupling the cart body to the fuel tank, a hose and a nozzle, a spill guard surrounding the nozzle, an electric pump for pumping fuel from the fuel tank to the customer vehicle via the hose and nozzle, and a display dock disposed on the cart body, the display dock configured to dock a computing device configured to display fueling parameters based on a customer fuel request received via a communications network.

A leak stop assembly for an automatic shut-off fluid nozzle having a fluid flow path and a check valve with a through bore in the flow path. The assembly includes a bleeder seat that houses a length of the flow path proximate the check valve, a rubber plug, and a rigid cross-brace attached to the bleeder seat and holding the plug. Fluid flows around the check valve when open. The cross-brace positions the plug relative to the check valve through bore such that the plug seals against the check valve through bore when the check valve is closed.

A method of deploying a water intake device in a fuel storage tank involves providing a water intake device having an elongate flow structure including at least one flexible flow tube and an elongate substrate adjacent to the flow tube, wherein the substrate provides a semi-rigid characteristic that allows the elongate flow structure to be guided. Another step of the method involves providing a guide tube having a straight portion and an arcuate portion at a distal end of the guide tube. Another step of the method involves installing the guide tube generally vertically into a fuel storage tank with the arcuate portion directed toward a desired guidance direction. Another step of the method involves moving the elongate flow structure of the water intake device through the guide tube into a deployed position.

A water intake device for use in a fuel storage tank comprises an elongate flow structure including a plurality of flexible flow tubes having respective first ends of different lengths and a second end at a common location. A header manifold is in fluid communication with the second ends of the flow tubes, the header manifold having a single connection port. In addition, the header manifold is configured to allow flow between the flow tubes and the connection port.
