Sea-Dog Gas Tank Vent, Black Injection Molded Nylon, 5/8 Inch Hose Barb - 357100-1

The Sea-Dog Gas Tank Vent (357100-1) provides the airflow needed to maintain proper fuel flow while filling and during use. As fuel is consumed and tank levels drop, or as temperature changes cause the fuel and air inside the tank to expand and contract, this vent compensates for those changes so the fuel system stays balanced. It is designed to prevent vacuum build-up during use, which can otherwise disrupt fuel delivery, and it also functions as a pressure release valve for the gas tank. By managing this airflow, the vent helps prevent fuel spills and blow-back, and it ensures fuel fumes vent outboard instead of building up inside the boat.

An integral 5/8 inch hose barb allows the vent to connect securely to vent hose without additional adapters, making it a straightforward fit for standard marine fuel vent lines. The vent is constructed of UV resistant injection molded nylon, so it holds up to sun and weather exposure in a marine environment without becoming brittle over time. It is finished in black. This is a small, lightweight fitting sized for compact vent line installations on boats and portable fuel systems.
