When the OCS is positioned properly, the cone of the screen is located at the top of the OCS. As the fuel vapors pass through the second screen, their velocity is decreased. The decrease in vapor velocity results in an increase in vapor pressure. This higher pressure helps the volatile fuel vapors to remain in a gaseous state. The less volatile water vapor condenses to a liquid, which is collected in the down tube. More of the volatile fuel vapors remain in a gaseous state, and are drawn into the air box, where they are consumed in the combustion process.

Detours has verified the collection of less fuel in the down tube after he flipped his OCS to the correct orientation.
