What function do vapor recovery nozzles serve?

• A. They increase the fuel delivery speed
• B. They monitor fuel quality
• C. They funnel vapors back into the storage tank during refueling
• D. They prevent spills during refueling

Answer: (C)

Vapor recovery nozzles play a crucial role in the refueling process by funneling vapors back into the storage tank. As fuel is dispensed, vapors generated from the fuel expand and rise. Without a vapor recovery system, these vapors would escape into the atmosphere, contributing to air pollution and potentially causing safety hazards. The correct function of vapor recovery nozzles is to capture these vapors and redirect them back into the storage tank, thereby reducing emissions and making the refueling process more environmentally friendly. This process not only helps in minimizing air pollution but also enhances fuel efficiency by preventing the loss of fuel vapor, which can otherwise escape and be wasted. Understanding this function is essential for anyone involved in the operation or maintenance of fuel dispensing equipment, as it directly relates to regulatory compliance and environmental protection efforts.
