In a vapor recovery balance system, where is the liquid removal device pick-up located?

• A. At the bottom of the dispenser
• B. At the breakaway
• C. In the hose loop between the dispenser and the retractor
• D. In the hose loop when the nozzle spout is inserted into the vehicle fill pipe

Answer: (D)

In a vapor recovery balance system, the liquid removal device pick-up is strategically located in the hose loop when the nozzle spout is inserted into the vehicle fill pipe. This positioning is crucial for effectively capturing and managing liquid fuel vapors that may be displaced during the fueling process.

When the nozzle is inserted into the vehicle's fill pipe, it ensures that any vapors that might escape as fuel is dispensed are promptly recovered and routed back into the storage system. This is essential for maintaining environmental compliance and minimizing air pollution, which is one of the primary goals of vapor recovery systems.

The design of the system allows for efficient liquid recovery, preventing the release of harmful vapors into the atmosphere and ensuring a smoother fueling experience for the customer. Hence, having the liquid removal device in this specific location maximizes the system's effectiveness in balancing the vapor and liquid phases during fuel dispensing.
