NFPA 110 (Standard for Emergency and Standby Power) Section 7.9.2 requires a fuel oil day tank be provided when the main tank is not close enough to the generator to provide sufficient suction head from the prime mover integral fuel oil pump. A day tank is also required if the engine manufacturer's fuel pump static head limits are exceeded when the main tank is at full fuel oil level.
Section 5.5.3 indicates minimum sizing requirements for the main tank, while other documents have maximum sizing allowances for the day tank. I cannot find minimum sizing requirements for the day tank in NFPA 110 or other codes and standards. Can someone point me in the correct direction? Submitted anonymously and posted for discussion.

Have you checked NFPA 20, Installation of Stationary Fire Pumps for Fire Protection? There is a conservative formula there and other requirements for day tanks.

NFPA 20 9.6.2.3 does not provide day tank requirements only the requirements for the fuel supply in general
