Attwood Marine 99FLB1401S Fill Limit Vent Valve with GRV Communication 1.4" Shutoff Grey

The Attwood Marine 99FLB1401S Fill Limit Vent Valve (FLVV) is a critical fuel system safety component designed to prevent overfilling and protect your vessel's evaporative emissions system. This 1.4-inch shutoff valve sets the maximum fuel level in your tank, ensuring fuel stays where it belongs during filling, operation, trailering, and storage.

Key Features:

• Prevents liquid fuel from reaching the carbon canister or vent system, protecting expensive evaporative emission components
• Integrated GRV (Gas Recirculation Valve) communication for proper fuel system venting
• 1.4-inch shutoff diameter for precise fuel level control
• Compatible with ethanol-blended fuels (E10, E15) and works with both plastic and aluminum fuel tanks
• Meets all USCG CFR 33 and ABYC H-24 fire test requirements
• Complies with CARB (California Air Resources Board) and EPA emissions regulations
• High-performance integrated gasket included for reliable sealing
• Assembly guide aligns the FLVV and gasket with tank opening for faster, easier installation
• Durable grey construction resistant to fuel and environmental exposure

This fill limit vent valve is essential for modern marine fuel systems, particularly on vessels with EPA-compliant fuel systems. By preventing fuel from entering the evaporative emissions system, it helps maintain system integrity, prevents fuel odors, and ensures regulatory compliance.
