In a balance Stage II vapor recovery system, where do vapors typically flow within the coaxial hose?

In a balance Stage II vapor recovery system, vapors flow through the outside pathway of the coaxial hose. This design is specifically engineered to facilitate the recovery of gasoline vapors during refueling. As fuel is dispensed into the vehicle's tank, the vapors from the tank are drawn into the coaxial hose and travel through the outer pathway.

This arrangement helps prevent the release of harmful vapors into the atmosphere, which is crucial for reducing air pollution and adhering to environmental regulations. Meanwhile, the inner pathway of the coaxial hose serves to deliver the fuel to the vehicle, ensuring a safe and efficient transfer.

The functionality of the outside pathway for vapor movement highlights the effectiveness of this type of vapor recovery system in maintaining a balance between product delivery and vapor recovery, minimizing environmental impact during the fueling process.
