Attwood 1607-3 Straight Fuel Tank Vent, White, 5/8 Inch I.D. Hose, 3/4-7/8 Inch Mounting Hole

The Attwood 1607-3 is a straight-style marine fuel tank vent designed to let air escape from the fuel tank during fueling and normal operation, preventing pressure buildup, fuel splash-back, and vapor lock. It connects to a 5/8 inch I.D. Vent hose and mounts through the hull using a 3/4 inch to 7/8 inch hole, making it a straightforward fit for both new fuel system installations and replacement of a worn or cracked vent fitting.

Built in White polypropylene, the 1607-3 resists corrosion, UV exposure, and the harsh conditions of continuous seawater and weather exposure, so it holds up to long-term deck or hull mounting without degrading. Its low-profile straight design keeps the exterior finish clean while providing reliable, unobstructed airflow to the fuel tank. As an integrated fuel system component, it is intended to work as part of a properly vented fuel tank setup on recreational boats.
