Attwood Fuel Vent Line Surge Protector, Black | Spill-Free Refueling

Smart, compact protection for marina refueling

The Attwood Fuel Vent Line Surge Protector (Black) is a small but effective marine accessory designed to help minimize fuel spills during refueling. Its clean, durable design fits a variety of boats and fuel systems, and the black finish complements most deck hardware for a discreet setup.

How it works

• Installs along the tank's vent line to guide fuel flow toward a safe shut-off point.
• Assists automatic shot-off nozzles by signaling when the tank is near full, potentially stopping the pump.
• For non-automatic nozzles, it provides an audible gurgling alert to indicate the tank is almost full.
• Built to be compatible with Ethanol blended fuels, reducing compatibility concerns on modern boats.
• Compact polypropylene body is clearly labeled to show which end connects on the vent side.
• Includes 2 hose clamps and connects to a 5/8-inch hose for simple installation.
• No hull mounting is required, simplifying installation and reducing vibration concerns.

What you get and basic specs

Real-world usage and benefits

Whether you’re fueling at a busy marina or a quiet cove, this surge protector provides a straightforward, non-intrusive safeguard against spills. The audible alert on non-automatic nozzles offers a helpful cue in noisy environments, while automatic nozzles may benefit from an added layer of pump shut-off control. Its deployment is designed to be quick and low-profile, so it won’t clutter deck space or interfere with other equipment.

As a practical marina accessory, it complements other safety and regulatory-compliant marine gear. The Attwood name reflects a long history of engineering and testing high-quality marine products, and this piece aligns with that tradition of reliability and ease of use. While results can vary with fuel type and refueling practices, many boaters appreciate the potential for reduced spills and a calmer fueling process.
