A system for supplying a liquid. A reservoir tank has a low level and a high level of the liquid. A pump is submerged in the liquid within the reservoir tank. The pump has an inlet to receive the liquid from a source outside of the reservoir tank and an outlet to deliver the liquid to a destination outside of the reservoir tank. A bleed path places the pump outlet in fluid communication with the reservoir tank. The bleed path has a bleed valve controlling the flow of liquid through the bleed path to maintain the liquid level in the reservoir tank above the low level. A recirculation path places the pump inlet in fluid communication with the reservoir tank. The recirculation path has a recirculation valve controlling the flow of liquid through the recirculation path to maintain the liquid level in the reservoir tank below the high level.

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.

A fuel storage and supply arrangement serving 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 and a pump assembly for drawing the fuel from the storage tank providing the fuel under pressure. A fuel supply line is configured to convey the fuel under pressure from the pump assembly to the at least one fuel dispenser in a dispenser flow path. A fuel conditioning and filtration assembly comprise a housing having a housing inlet receiving the fuel under pressure created by the pump and a housing outlet whereby the fuel entering the housing inlet exits the housing through the housing outlet. A filter element is within the housing and interposed in the flow path between the housing inlet and the housing outlet. A return tube receiving fuel from the outlet of the housing is also provided. An agitator manifold receiving the fuel from the return tube and having an agitator tube defining a plurality of agitation holes, the agitator tube being positioned proximate to the bottom of the fuel storage tank. In addition, the agitator manifold is movable between an insertion orientation and a deployed orientation. A flow control valve is provided for controlling the flow of the fuel along the fuel conditioning and filtration flow path.

A method and apparatus are provided for controlling a fuel delivery system to limit acidic corrosion. An exemplary control system includes a controller, at least one monitor, an output, and a remediation system. The monitor of the control system may collect and analyze data indicative of a corrosive environment in the fuel delivery system. The output of the control system may automatically warn an operator of the fueling station of the corrosive environment so that the operator can take preventative or corrective action. The remediation system of the control system may take at least one corrective action to remediate the corrosive environment in the fuel delivery system.
