Economy Day Tanks were designed to fit the demand for a "basic" day tank. Customers and specifying engineers required a transfer pump and motor located on the tank, but did not require the tank to have any other signals, relays or lights. Our Economy Day Tanks are a simplified version of the Automatic Day Tank. The tanks come standard with a fuel level gauge, 2" manual fill connection, 2 GPM pump with 1/3 HP motor, and a level switch that automatically maintains the fuel level in the tank.
