Data are received indicating an amount of pumped fuel provided to a vehicle fuel tank. A vehicle fuel tank fuel volume is received. Upon determining that a difference between the pumped amount of fuel and a detected change in a fuel volume in the fuel tank exceeds a threshold, a fuel pump is deactivated.

A mobile device for discharging a liquid-filled container is disclosed. The device has a closable compartment provided with a closable opening, and an unloading installation in the inner space of the device, coupleable with the container. The unloading installation is able to extract liquid from the container via top unloading and to move it outside of the device, and includes an absorption means for removing liquid vapors which is connectable with the container for the extraction of top liquid vapors. A method for discharging liquid containers, such as unloading benzyl chloride liquid with the mobile device, is described.

A fuel storage system has a tank access chamber with improved monitoring, servicing and maintenance capabilities. In particular, the chamber includes a sump monitored by a liquid sensor whose proper function can be automatically checked remotely, e.g., via an electronic controller or remote manual operation. In cases where such a check indicates a need for physical inspection of the sump sensor, the present system provides for sensor removal and installation by service personnel from a location outside the tank access chamber. Thus, the present system facilitates regular inspection and routine or unplanned maintenance without the need for a person to physically enter the tank access chamber.

Fuel management systems for a fuel dispensing facility including a fuel delivery system are disclosed. The fuel delivery system includes at least one storage tank configured to contain a fuel, at least one dispenser configured to receive the fuel from the at least one storage tank, and a fuel handling system which is configured to one of (1) deliver the fuel to the at least one storage tank, (2) receive the fuel from the at least one storage tank, (3) monitor for a leak within the fuel delivery system, and (4) monitor for a fuel inventory within the fuel delivery system. The fuel management system may include installation records of the fuel handling components. The fuel management system may monitor cameras positioned in sumps of the fuel delivery system. The fuel delivery system may include a camera positioned to monitor an interior of a sump, the interior of the sump being provided by a sump basin and a sump cover. The sump cover may be a sump lid. The sump cover may be a dispenser. The sump cover may be another portion of the fuel delivery system.

To provide a safety joint capable of preventing moment generated by swinging of a filling hose from acting on the safety joint and surely separating the safety joint to a hydrogen filling apparatus side member and a vehicle side member when a tensile force more or equal to a predetermined value is applied to the filling hose. The safety joint 100 according to the present invention includes a plug (10) with a cylindrical shape in which a passage (1A) is formed, a socket (20) in which a passage (21A) continuing to the passage (1A) in the plug (10) is formed, and a shut off valve mounted on the passage (21A) in the socket (20), the shut off valve opening when the plug (10) being inserted into the socket (20) and closing when the plug (10) being disconnected therefrom, wherein central axes of the passages of the plug and the socket form a straight line, a filling hose (61) is connected to the plug (10), and a hose guide (70) for limiting movement of the filling hose (61) at a position separated from the plug (10).

Methods for testing the integrity of a containment sump in contact with a matrix with a testing apparatus are provided. The testing apparatus may include an underground fixture positioned in contact the matrix, a test chamber, a conduit structure providing fluid communication between the underground fixture and the test chamber, and a pressure source for exerting a pressure that is communicated to the underground fixture via the conduit structure. In some embodiments, a method may include: releasing a test media into the containment sump; generating a negative pressure within the testing apparatus for a time period; and testing for the presence of test media within the testing apparatus. In other embodiments, a method may include: releasing a test media into the testing apparatus; generating a positive pressure within the testing apparatus for a time period; and testing for the presence of test media within the containment sump.

A product delivery system includes a product transport vehicle having at least a plurality of tank compartments, internal valves, control valves, fluid property sensors, temperature sensors, overfill sensors, pressure sensors, a system controller, and a memory module. The product delivery system may be operable to communicatively connect with the loading system at a loading station, a fleet management system, or a cloud system to obtain information, such as the amount of liquid product to be loaded into a tank compartment. The product delivery system may be operable to compare the volumes of the tank compartments with the amounts of liquid product to be loaded at a loading station and maintain the internal valve or control valve in a locked state or transition the internal valve or control valve to an unlocked state based on the comparison. Other comparisons based on liquid type or distribution tank volume can also be made.

A system of multiple non-manifolded fuel tanks on a portable platform and preferred embodiments which allow for improved access to the contents of each fuel tank, ability to transport multiple fuel types in a single system on a vehicle without towing apparatus, and the ability to maneuver the system via a forklift.

A removable fuel handle brace is provided, comprising: a pair of parallel horizontal sides, each having a hook on an inner end bent approximately 180 in a first direction; a pair of parallel vertical sides having a first end extending from an outer end of each horizontal side approximately 90 in a second direction opposite the first direction; an upper cross-piece connecting second ends of the vertical sides; a lower cross-piece having first and second ends connected to the vertical sides between the first and second ends of the vertical sides; and a pair of horizontal extensions connected to the first and second ends of the lower cross-piece and extending in a direction towards the hooks parallel to the horizontal sides.

Improvements in a portable vehicle fueling kiosk is disclosed. The kiosk is constructed on a pallet or a skid that allows the kiosk to be placed, located or moved to a location where the fuel dispensing is desired. A fuel tanker that would normally dispense fuel to a storage tank of a gas station is connected to one side of the kiosk. The kiosk accepts payment by nearly any form of money, credit card or token to measure, dispense and bill or invoice the user. The kiosk can have a Wi-Fi or cellular communication to communicate with a user at a distance and can monitor, use, status and remaining fuel in the tanker. If a fuel tanker has been depleted additional tankers can be connected to the kiosk, and when the kiosk is no longer needed it can be transported to another location.
