Marine Fuel Tank Vent with a Double Bowl/Cup design, constructed from highly durable 316 marine-grade stainless steel.
Key Differences & Functional Benefits
• Enhanced Splash Protection: The "double bowl" configuration provides an extra physical barrier. This significantly reduces the chances of raw fuel splashing up out of the vent line during high-flow fueling or when the tank sloshes in rough seas.
• Water Intrusion Prevention: The secondary cup layer helps trap exterior spray or rainwater coming in through the face, channeling it away or letting it drain before it can contaminate your fuel or water lines.
• Low-Profile Styling: Like standard flush mounts, it sits close to the boat's hull or transom to keep dock lines, fenders, or clothing from catching on it.
Specifications & Fitment
• Hose Barb connection: Features a standard multi-ridged tail piece, most commonly sized for a 5/8" (16mm) marine fuel vent line.
• Mesh Screen: Houses a permanent, integrated stainless steel mesh screen tucked underneath the solid central cap to act as a spark arrestor and a barrier against mud daubers, wasps, or other insects.
• Hardware Included: Ships with a heavy-duty rubber O-ring/gasket resting on the bowl's shoulder to form a tight seal against the exterior hull skin, clamped tightly in place by a bottom hex locking nut.
