Sea-Dog Line 3520301 90-Degree Gas Tank Vent Machined Brass Chrome Plated 9/16"

The Sea-Dog Line 3520301 is a 90-degree marine gas tank vent crafted from machined brass with a chrome-plated finish. Designed for use on boats and watercraft with a 9/16" hose fitting, this vent maintains proper airflow to support consistent fuel delivery during filling and underway operation.

Gas tank vents play a critical role in marine fuel systems. By allowing air to freely enter and exit the tank, this vent compensates for fuel level changes caused by consumption as well as pressure fluctuations from temperature-related expansion and contraction. It also helps prevent vacuum build-up that can disrupt fuel flow, and acts as a pressure relief valve to reduce the risk of fuel blow-back and fume accumulation inside the vessel.

Key Features:

• Material: Machined brass with chrome-plated finish for corrosion resistance and a polished appearance
• Angle: 90-degree hose barb connection for tight or angled installations
• Hose Size: Fits 9/16" vent hose
• Function: Prevents vacuum build-up and acts as a pressure release valve for the fuel tank
• Helps prevent fuel spills, blow-back, and ensures fumes are vented outboard
• Suitable for gasoline fuel tank ventilation on marine vessels

The Sea-Dog 3520301 is a reliable, cost-effective solution for maintaining a safe and properly functioning marine fuel system.
