Overview

The Attwood Marine 1607-3 is a straight fuel tank vent for boats that lets air escape from the tank while you refuel. It connects to a 5/8 inch I.D. vent hose, fits a 3/4 inch installation hole, and works with hull sections up to 7/8 inch thick.

The body is black polypropylene with splash-resistant construction that also stands up well around saltwater and wet hull sides. It meets ABYC ventilation specifications, which matters when you are replacing a vent in a fuel system that needs to stay safe and properly vented at the dock and underway.

Key features

• Straight vent body for fuel vent runs that come to the hull fitting without a built-in angle
• Fits 5/8 inch I.D. hose, which is a key sizing point before ordering a replacement
• Mounts in a 3/4 inch hole and accepts hull thickness up to 7/8 inch
• Black polypropylene body resists splash exposure and corrosion around the fuel fill area
• Meets ABYC ventilation specifications

Installation and fit

This vent is a good match for boats that already use a straight hull-side fuel vent with 5/8 inch hose. Before ordering, check the hose inside diameter, the existing mounting hole, and the thickness of the panel or hull section where the vent passes through.

For replacement work, the straight layout matters just as much as the hose size. If your current vent line reaches the hull fitting in a direct run, this style keeps the install simple and avoids forcing the hose into a bend right at the connection.

Use on board

This part suits boats with a conventional vented fuel tank setup, including many runabouts, center consoles, pontoons, and small cruisers. It makes sense for owners replacing an older vent that is faded, cracked, or no longer the right match for the hose and mounting hole already in the boat.
