90° Fuel Tank Vent – Stainless Steel Deck Vent Ø15 mm

This stainless steel deck vent ensures safe and efficient ventilation for your boat’s fuel tank under all operating conditions. As fuel expands during heat or when refueling, fumes and pressure build up – the 90° vent reliably channels these vapors out of the hull, preventing your tank from pressurizing or bursting. Likewise, as fuel is consumed, the vent allows air back in to avert vacuum formation. The result is smooth engine performance and safe refueling without the risk of fuel spray or backsplash through the filler cap.

The right-angle design facilitates installation on a vertical hull surface – your vent hose connects without sharp bends. The ~15 mm inner diameter matches widely-used fuel vent hoses, making this component universally compatible with most systems. A threaded neck (~19 mm) with locking nut secures the vent firmly in place, and an included gasket seals out water ingress.

Quality & Durability: The base and hose barb are made of polished 316 stainless steel, which stands up to continuous contact with gasoline, diesel, and saltwater. This ensures the vent won’t rust or contaminate your fuel over time. The outer cap is crafted from tough UV-stabilized plastic that won’t crack or fade under sun exposure. Beneath the cap resides a fine metal mesh screen – a crucial safety feature that stops flames or sparks (from static discharge or external fire) from traveling into the tank.

Applications: Suitable for all types of motorboats and yachts with gasoline or diesel fuel systems. It’s an excellent upgrade when replacing an old or corroded vent – the stainless model improves reliability and appearance. It can also be used on stationary fuel tanks for generators or any vessels requiring a 15 mm vent outlet.

Installation: Choose a high point on the hull, away from direct water spray, and drill a hole to fit the vent’s threaded neck (~19–20 mm). Insert the vent so the threaded portion extends inside, then tighten the provided nut from the inside. Attach a 15 mm ID vent hose to the barb and secure it with a hose clamp. Ensure the hose runs smoothly downward to the tank with no kinks.

For maintenance, periodically inspect the vent opening for obstructions (such as salt crust or insect nests) and clean the mesh screen if needed. Thanks to its quality materials, this vent will provide trouble-free service for many years with minimal upkeep.

• Safe Fuel System: Maintains continuous airflow into and out of the tank, preventing engine fuel starvation and unwanted pressure build-up
• Reliable Performance: Corrosion-proof and UV-resistant – built to withstand harsh marine environments and long-term use
• Low-Profile Design: Sleek, flush-fit cap sits close to the hull, reducing snagging hazards and damage risk
• Easy Integration: Standard hose size and universal design make it simple to retrofit into most boat fuel systems
• Safety Compliant: Meets fuel ventilation requirements (including flame arrestor inclusion), contributing to overall onboard safety
