Moeller 033806-10 Anti-Siphon Valve for Marine Fuel Systems

The Moeller 033806-10 is a marine-grade anti-siphon valve designed to prevent fuel siphoning in permanent fuel tank installations on gasoline-powered boats. Required by Federal Law and the U.S. Coast Guard, this essential safety component ensures compliance while protecting your vessel from fuel system hazards.

Key Features:

• Provides Coast Guard and industry-standard anti-siphon protection for all gasoline-powered boats
• Combines anti-siphon functionality with convenient hose barb design for easy installation
• Constructed from durable materials to withstand harsh marine environments
• Ensures compliance with federal regulations and USCG requirements for permanent fuel tank installations
• Prevents fuel from siphoning back through the fuel system

Important: This valve is designed exclusively for marine fuel systems and must NOT be used in potable water systems. Select the appropriate calibration based on your engine's horsepower rating: brass valves (model 15) for engines 200 HP and above, or aluminum valves (model 30) for engines below 200 HP.

This critical safety device helps prevent fuel leaks and environmental contamination while ensuring your boat's fuel system meets all regulatory standards.
