The RONCO6590DC states its whole design in its name: a 65 gallon primary tank inside a 90 gallon containment basin. That spread between inner and outer capacity is the safety margin - the basin can take the primary's entire contents and still have freeboard, which is the difference between containment that satisfies an inspector and containment that merely gestures at the idea.
It is the compact member of the standard DC line, a fit for day-tank chemical feed duty beside a dosing pump. Contents at full water weight run about 542 lb on an assembly that ships at 105 lb; a flat mechanical-room floor carries it without ceremony, and the footprint stays close to the tank itself because the basin is the footprint.
As with every Ronco tank since 1974, fittings are installed per order at the Tustin, California plant - spin-welded or threaded to your marks. Print the drawing below, sort out suction height and fill access against your pump, and finalize with the on-page fitting planner.
