Water and Fuel Systems Maintenance (WFSM) Set A Volume 3 Practice Test

The purpose of a fuel vapor recovery system is to capture fuel vapors during refueling processes. This system is crucial for environmental protection and compliance with regulations regarding air quality. During the refueling of vehicles, gasoline and other fuels can evaporate and release volatile organic compounds (VOCs) into the atmosphere, contributing to air pollution and smog formation. By using a fuel vapor recovery system, these vapors are collected and either returned to the storage tank or processed to minimize emissions. This not only helps to reduce environmental impact but also improves safety by minimizing the risk of explosive vapor accumulation in the refueling area.

Other systems, such as monitoring fuel quality or preventing leaks, serve different purposes that do not directly relate to vapor capture during the refueling process.
