I have to agree with Huzefa – use the larger number. In re-reading the code, I would go even farther. The code refers to “volume” without making any clarification on vapor volume or total pit volume. Without that clarification, the only reasonable approach is to use the volume of the pit, not the volume of the vapor space.
