Method for autonomously fueling machinery operating at fracking sites. A fuel tank with a plurality of fuel lines individually coupled to a fuel tank are used. Pumps are connected to some of the fuel lines. Pump outputs are coupled to hoses extending to machinery tanks to be refueled. A cap is detachably connected to the hoses and machinery tanks to be fueled. The fuel tank includes an intake filter capable of blocking approximately 10 micron contaminants with about 250 gallon per minute flow rate. The methodology of the present invention includes measuring the duration of machinery tank fuelings and the interval between fuelings. A first alarm is generated if the duration of fuelings is longer than a first interval. A second alarm is generated if the interval between fuelings is longer than a second interval.

A vapor control set screw valve applied into the handle of a fuel dispensing nozzle, including a valve bushing intermediately applied within the vapor return line within the handle, a set screw valve provided within the lateral channel formed of the bushing, an insert bushing applied to the dispenser handle, and the set screw, forming the valve, engaging within the insert bushing, and extending into the vapor return line bushing, to provide for its adjustment therein, to open or close the vapor return line within the nozzle in order to regulate and control the flow of the returning vapors being pumped back to the associated dispenser, and to the normally underground fuel storage tank associated with gasoline dispensing.

Certain embodiments of the present invention provide a fill gun apparatus for interconnection of a pump truck and a pressurized liquid delivery system. The fill gun apparatus can be easily attached and detached from an inlet port to deliver a pressurized fluid, for improved delivery, increased efficiency, increased safety, and decreased waste.

The present invention relates to a system and assembly for refilling a reservoir with liquid dispensed from a dispenser, in particular, but not exclusively, to a system and assembly for the substantially leak-free refilling of the reservoir of a smoking-substitute device with a liquid comprising nicotine from a refill dispenser. The assembly is configured to provide a gas communication pathway through the assembly and physically separate from the liquid communication pathway for venting gas from an end of the assembly proximal the first aperture to an exterior of the assembly responsive to the movement of the assembly to the secured and open configuration, the assembly configured to close the gas communication pathway in the unsecured and closed configuration.

The present invention solves some of the problems of the prior art by providing a method, system and apparatus for readily refilling the reservoir of a smoking-substitute device with liquid from a dispenser. The method, system and apparatus of the present invention prevents liquid from being dispensed until the dispenser is securely and sealably engaged to the smoking-substitute device, provides independent liquid and gas pathways between the dispenser and reservoir, and substantially alleviates the problems of spillage and/or leakage when dispensing liquid from the dispenser into the reservoir of the smoking-substitute device.
