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 engines of the equipment to be refueled. Adapters allow connection of the distal end of each hose or conduit to an inlet of the suction side of the engine. Adaptors also allow connection of the return side of the engine's fuel system back to the central storage tank. Thereby mechanically allowing flow from the central storage tank, through the engine's fuel system, supply fuel for the engine to burn and allowing the return or unburned fuel a path back to the central storage tank.

A removable liquid transport assembly configured to be readily installed in and removed from a liquid dispenser to permit the liquid dispenser to be readily sanitized. The removable liquid transport assembly preferably includes a liquid manifold, a valve assembly and a pump head. The removable liquid transport assembly is configured such that liquid can flow in a first direction through the removable liquid transport assembly to permit a liquid to be dispensed from a liquid dispenser and liquid can flow in a second direction back to a liquid storage container to prevent damage to one or more components of the liquid dispenser.

A system for filling an LPG vehicle with LPG using an auxiliary bombe is provided. The system may be configured for easily filling a main bombe with LPG even in the hot season (summertime) or the like during which the outside temperature rapidly rises, by using an auxiliary bombe in addition to using the main bombe. The system may also be capable of always smoothly refilling the main bombe with LPG by moving a portion of the LPG in the main bombe to the auxiliary bombe, when the pressure in the main bombe is higher than the LPG filling pressure of a filling gun in the hot season during which the outside temperature rapidly rises, so that the pressure in the main bombe becomes lower than the filling pressure.

A method of aseptically distributing fluid to a plurality of vessels includes securing the plurality of vessels relative to a hub and flowing fluid through an input tube into a plenum of the hub such that a substantially equal amount of fluid flows from the plenum into each of the vessels simultaneously. The vessels are positioned in the same plane relative to one another with each vessel having an inflow conduit extending from the hub to the vessel such that an arc segment is formed between the hub and the vessel.
