An improved fill cap for delivering a fluid from a fluid transporting mechanism to a fluid tank is disclosed. A connection plate is coupled to an opening of the fluid tank and a probe is disposed within the fluid tank and coupled to the connection plate at a first distal end. The fluid flows into the fluid tank through an outlet at a second distal end of the probe. A valve is disposed at the second distal end of the probe and is movable between an open position and a closed position to control fluid flow out of the probe outlet. An arm is coupled to the valve and moves the valve between the open and closed positions and a float is coupled to the arm that moves the arm depending on the level of fluid in the fluid tank.

A holding stand for a multicoupling for filling and/or emptying a chemical plant container is provided, having a mounting device for the essentially stationary fastening of the holding stand and at least one compensating device, couplable indirectly or directly to the multicoupling, for varying a position of the multicoupling in relation to the mounting device in the vertical direction and/or in the horizontal direction and/or for varying an angular position of the multicoupling in relation to the mounting device about a vertical and/or horizontal axis of rotation. It thereby becomes possible for a multicoupling to be coupled simply.

Systems and methods for hot refueling from a fuel source to one or more fuel tanks associated with equipment in the hot zone of a well site. Automatic valves are located at the fuel tanks, obviating the need for electronic communication in or out of the hot zone. A flexible conduit or hose is connected between one or more outlet ports of the fuel source to corresponding one or more automatic valves at the fuel tanks. The valve, such as a float-type valve, uses fuel level to open the valve whenever the fuel tank is below a full fuel level threshold. Fuel levels at or above the full fuel level threshold automatically close the valve.

An object is to enhance the assembly of a breather pipe which is accommodated in a filler pipe.

A nozzle guide (10, 10a, 10b) that is arranged within a filler pipe (110) includes: a main body portion (20, 20b) that guides the insertion and removal of a refueling nozzle (150); and a connection member (50, 50a to 50c) that is provided on an outer circumferential surface (27) of the main body portion (20, 20b) and in which an upper end portion (51) of the connection member is located, in a tank direction (TD) extending from a refueling port (FC) toward a fuel tank (FT), on a downstream side with respect to a tip end portion (152) of the refueling nozzle (150), and the connection member (50, 50a to 50c) includes: a connection portion (52, 52a) connected to a breather pipe (120) that is arranged within the filler pipe (110); and a vapor flow path formation portion (55, 55b, 55c) that forms part of a vapor flow path (220) for the fuel vapor that flows in through the breather pipe (120) and the connection portion (52, 52a).

In a method and system for delivering fluid to a fluid consuming asset having a fluid tank, an inlet of a manifold is fluidically coupled to a tank and an outlet of the manifold is coupled to a spigot. A pressure relief valve is disposed between the tank and the manifold to facilitate fluid flow back to the tank through a recirculation inlet when the back-pressure in the system reaches a threshold value. A first distal end of a fluid transporting mechanism is coupled to the spigot and a second distal end thereof is coupled to a hydraulic connector of a fill cap having a connection plate coupled to the fluid tank of the fluid consuming asset. The fill cap further comprises a probe and fluid flows from the first tank to the second tank, through the manifold and the hydraulic connector, through the probe and into the fluid tank of the fluid consuming asset.
