An example fuel cap assembly includes a fuel cap, a sensor element extending from the fuel cap, and a fuel tube extending from the fuel cap next to the sensor element. The fuel tube includes an outlet end having at least one side-diverting fuel outlet that extends through a sidewall of the fuel tube. A fuel cap assembly kit and method of filling a fuel tank are also disclosed.

The present disclosure relates to a service station that is transportable over a predetermined roadway or by water. The service station has a base having a stern, bow, and two lateral sides. The base is configured to displace a volume of water so as to render the service station buoyant. A tank is disposed on the base and is configured to contain fuel. The tank is configured to comply with U.S. Government requirements for transportation of fuel over roadways. A pump is disposed on the base, and is configured to dispense liquid fuel to supply vehicles. An axle assembly is coupled to the base and has at least one wheel, the at least one wheel and axle assembly moveable between an engaged position and a stored position. The least one wheel is in contact with a surface and partially supports the base over the surface in an engaged position.

A trailer-mounted pumping system includes a flatbed trailer having a generally flat deck surface, a pump, a batch controller, and a metering device in electronic communication with the batch controller, wherein the pump is configured to move a liquid from at least one tote supported by the generally flat deck surface to a location off-board the flatbed trailer, and the batch controller is configured to measure a volume of the liquid via the metering device. The pump, the metering device, and/or the batch controller may be disposed beneath the generally flat deck surface.

A fluid delivery system includes a distribution station moveable between a first location and a second location, a pump on the distribution station, at least one manifold on the distribution station and fluidly connected with the pump, a plurality of hoses connected with the at least one manifold, each of the hoses including a tube and a protective sleeve that circumscribes the tube, a plurality of valves on the distribution station, each of the valves situated between the at least one manifold and a respective different one of the hoses, a plurality of fluid level sensors, each of the fluid level sensors being associated a respective different one of the hoses, and a plurality of sensor communication lines. Each of the sensor communication lines is connected or connectable with a respective different one of the fluid level sensors. Each of the sensor communication lines is routed with a respective different one of the hoses. Each of the sensor communication lines is secured to the tube of one of the hoses by the protective sleeve.

A system and method for fueling multiple saddle tanks of hydraulic fracturing equipment from a single self-propelled cart. The cart having multiple retractable fuel lines for providing and obtaining fuel. Each retractable fuel supply line uses a flowmeter, a ball valve, and an electrically actuated valve to provide remote control to a controller based on a user's selected fueling requirements. An electronic reporting system provides fuel data to operators and users. Fuel data such as fuel tank status, an amount of fuel usage over a stage level, a daily level, or job level along with a fill level of the fuel tank.

A gravity-fed fuel delivery system is provided. A central storage tank holds fuel to re-supply a number of pump trucks or other mechanized equipment, such as on a hydraulic fracturing location, and can be selectively raised or lowered. Hoses or other conduits extend from the central storage tank to individual fuel tanks of the equipment to be refueled. Adapters allow connection of the distal end of each hose or conduit to an inlet opening of a fuel tank. A float valve assembly senses when fuel inside an individual fuel tank is below a predetermined level, thereby mechanically opening a valve assembly to permit fluid to flow from the central storage tank, through a conduit, through the float valve assembly and into the fuel tank.

A method for delivering heating oil to homes and commercial establishments comprises a two-mode combination of (a) using a conventional large-tank delivery truck and (b) using a portable, self-contained apparatus which is carried on a lighter weight truck as cargo. The portable apparatus comprises a tank having just under 119 gallons capacity, a pump for flowing oil through a meter subsystem which measures the quantity of oil, to a hose; all mounted on a skid for portability. The apparatus is capable of dispensing oil quantities of 1, 5, or 25 gallons while meeting regulators' weights and measures approval requirements. When the small tank is filled with heating oil, preferred apparatus weighs less than 1500 pounds and is removably carried on the bed of an un-placarded truck (one that does not have to meet hazardous material requirements), and that may be driven by a driver having an ordinary driver's license, compared to the requirements and associated costs attending the conventional truck.

A mobile fuel delivery system and method are described for dispensing fuel in a poorly ventilated area. The system includes a fuel dispensing nozzle for dispensing the fuel; a cargo tank 16 for containing the fuel; a vapour recovery nozzle for recovering vapour from a fuel tank of a vehicle during fuelling; a sealing mechanism for sealingly engaging the fuel tank, a vapour tank 18; a pressure/vacuum release valve 20 connected between tank 16 and tank 18 and which is operable to increase/decrease pressure within tank 16 during dispensing of fuel and recovery of vapour recovered by the vapour recovery nozzle and pumped into the tank 16; and a safety mechanism including a control module 38 and a pressure detector 36 for detecting pressure within the tank 18, the module 38 being operable to stop fuel dispensing when pressure in tank 18 reaches a predetermined pressure.

A distribution station includes a mobile trailer, a pump on the mobile trailer, at least one manifold on the mobile trailer and fluidly connected with the pump, and a plurality of reels on the mobile trailer. A plurality of hoses are connected with different ones of the reels. A plurality of valves on the mobile trailer are situated between the manifold and respective different ones of the reels. A plurality of fluid level sensors are associated with different ones of the hoses. A controller is configured to individually open and close the valves responsive to the fluid level sensors, and a satellite dish is mounted on the mobile trailer. The satellite dish is moveable between a stowed position and a deployed position.
