The present disclosure is directed to devices for dispensing liquid, especially fuel. In one embodiment, a device for dispensing fuel includes a spout for pouring liquid fuel, an annular fitting including a chamber formed therein. A sealing surface, a stopper, and spring may be disposed within the chamber. The annular fitting may be attached to the spout. The annular fitting may be configured to mate with a portable fuel canister. The fitting may include sidewalls forming a channel for liquid fuel, an outer wall enveloping a portion of the sidewall forming a chamber proximate the liquid channel, and an atmospheric orifice formed in the outer wall. The sealing surface may be disposed proximal the orifice. The spring may be configured to bias the stopper into contact with the sealing surface such that the chamber is in selective pressure-dependent fluid communication with an atmosphere outside the device.

Liquid container nozzles including a valve handle, valve body, spool, and spout assembly, where the valve body may move slidingly into the valve handle over the spool to control the flow of liquid through the nozzle. Liquid flow may be controlled by adjusting the position of the valve body in relation to the valve handle and spool using varying force or pressure. The spool may include one or more holes to control the flow of liquid. In some examples of the invention, the spool may narrow in an S-shaped fashion, and the holes of the spool may be located on a portion of the spool that narrows to form S-shaped holes. These holes may swirl liquid as it is poured from the nozzle to create a more uniform flow.

A refueling method for supplying fuel to at least one piece of fracturing equipment by installing a main fuel source at a fractionation operation, connecting the main fuel source to fracturing equipment to provide downhole fluids to the well, and connecting at least one pressurization unit to the main fuel source. The method includes using a supply coupling device for receiving fuel from one or more supply fuel lines in communication with the main fuel source and providing the fuel to a motor. The method includes using a return coupling device for receiving fuel from the motor and transferring the fuel through one or more return fuel lines to the main fuel source.

A distribution station includes a mobile trailer, a pump, a manifold, a fluid line connecting the pump to the manifold, and a bypass line leading into the fluid line between the pump and the manifold. The bypass line permits fluid to be provided to the manifold without use of the pump. Reels on the mobile trailer are individually connected with the manifold, and hoses are connected with a different one of the reels. Valves on the mobile trailer are situated between the manifold and different ones of the reels. Fluid level sensors are connectable to the ends of different ones of the hoses. A controller is configured to individually open and close the valves responsive to the fluid level sensors.
