Many classic cars hot rods boats and custom builds use open vent systems that allow fuel vapors to escape directly into the air.

Why Fuel Tanks Need Proper Venting Fuel tanks must be vented to allow air to move in and out as fuel levels change. When fuel warms up or expands vapors build pressure inside the tank. The vent system releases this pressure so the tank can operate safely and prevent vacuum conditions during fuel consumption.

Over time this can lead to strong fuel odors in enclosed spaces and may even create safety concerns. What Is a Fu...
