A permanent test port mounting in a conventional gasoline/diesel fuel dispenser to provide a technician access to the fuel line and perform various tests that enables testing to occur at a highline point in the line system to include all or at least more of the line system head pressure than has been possible before. In particular, the test port has a quick connect/disconnect fitting disposed in a collar intermediate a mounting for a filter in a conventional gasoline/diesel fuel dispenser and the filter to provide a technician access to the fuel line and perform various tests. The quick connect/disconnect fitting may also be coupled to a hose for draining fuel under pressure into a safety can to prevent spillage during replacement of the filter. The safety can may be emptied into the fuel tank to conserve the fuel, prevent polluting the environment and as a safety measure.

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 of delivering a fluid to a fluid consuming asset having a fluid tank is disclosed. A first tank is filled with the fluid and is fluidically coupled to a second tank which may be pressurized by a compressor. The second tank is fluidically coupled to a manifold which is in turn coupled to a fluid transporting mechanism. The fluid transporting mechanism is fluidically coupled to a hydraulic connector of a fill cap which is coupled to an opening of the fluid tank. The fluid is directed from the first tank to the second tank, the manifold, the fluid transporting mechanism, the hydraulic connector and into the fluid tank through an outlet of a probe of the fill cap.

A fuel transport sensor system for precise loading and unloading of fuel for transports includes a transport computer configured to be coupled to a fuel transport having a plurality of fuel compartments. Each of a plurality of load head sensors is in operational communication with the transport computer and coupled to one of a plurality of load heads. A load arm sensor coupled to a load arm and the load arm sensors communicate with the transport computer to track which fuel compartment is being filled with what fuel type. A pair of hose sensors coupled to a delivery hose confirm the delivery hose is connecting the load head with the correct fuel type for an in-ground storage tank before allowing a fire valve of the load head to be opened.

System, methods, and other embodiments described herein relate to controlling a fuel dispenser. In one embodiment, a method of controlling a fuel dispenser includes broadcasting a pairing signal to a vehicle, receiving, from the vehicle, a confirmation signal confirming completion of a pairing process between the fuel dispenser and the vehicle, transmitting, subsequent to the confirmation signal, a disable signal to the vehicle in response to data from one or more proximity sensors indicating that the vehicle is within a threshold range and a determination that the vehicle is refueling, and transmitting an enable signal to the vehicle in response to a determination that the vehicle is no longer refueling. The disable signal disables a moving capability of the vehicle, and the enable signal restores the moving capability of the vehicle.

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.

A conversion frame assembly configured to secure a fuel dispenser to a concrete pad and direct leaked fuel from the fuel dispenser into a sump at least partially embedded in the concrete pad. The conversion frame assembly includes a frame having a fluid passageway and a splash lip extending upward from the base plate and around the fluid passageway. The conversion frame assembly also includes a drainage tray configured to be coupled to the splash lip of the frame. When the drainage tray is coupled to the splash lip of the frame, an upper surface of the drainage tray defines a weir sloping inward and downward toward the fluid passageway in the base plate.

A fuel nozzle retainer kit includes a first retainer that is attachable to a fuel tank that has a skirt thereon. The first retainer extends over a fill port on the fuel tank. Additionally, the first retainer has elastomeric properties to engage and thus retain a fuel nozzle in the fuel port. A second retainer is attachable to a fuel tank that does not have a skirt thereon. The second retainer has a first portion that is mountable around a fill port of the fuel tank that does not have a skirt. The second retainer has a second portion which is pivotally coupled to the first portion. Additionally, the second portion is positionable to engage a fuel nozzle inserted into the fill port to retain the fuel nozzle in the fill port.

A spill prevention plug is provided. A plug body has an interior side and an exterior side with a threaded aperture that extends from the interior side to the exterior side of the plug body. The interior side of the plug body is removably attachable to a hose. A bushing threadingly engages the threaded aperture. A one way valve with a first end and a second end is provided with the first end of the one way valve engaging the bushing from the exterior side of the plug body. The one way valve being movable between an open position in which fluid flows through the one way valve from the interior side of the plug body to the exterior side of the plug body and a closed position in which fluid is prevented from flowing through the one way valve. An adapter for connection to a pump engages the second end of the one way valve.
