A distribution station includes a mobile trailer that has outer walls that enclose at least one interior compartment and the outer walls contain at least an exterior shell and thermal insulation adjacent the exterior shell. There is a pump, at least one manifold fluidly connected with the pump, a plurality of reels, a plurality of hoses connected with different ones of the reels, and a plurality of valves on the mobile trailer. Each valve is situated between the manifold and a respective different one 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.

A fuel storage and supply arrangement serves as a source of fuel to be dispensed via at least one fuel dispenser in a fuel dispensing environment. The arrangement comprises a storage tank for containing a quantity of the fuel, fuel piping configured to convey fuel from the fuel storage tank to a fuel dispenser, and a fuel conditioning and filtration assembly having an inlet in fluid communication with the fuel piping and an outlet in fluid communication with the fuel storage tank to return the fuel. A fuel conditioning and filtration element is interposed between the inlet and the outlet, the fuel conditioning and filtration element being configured to remove water from the fuel passing through the filter element. A flow valve allows and prevents flow of fuel through the filter element. Processing circuitry is operative to control the flow valve based on predetermined criteria.
