Moeller Anti-Siphon Valve for Marine Fuel Systems

The Moeller anti-siphon valve (ASV) protects permanent marine fuel tank installations on gasoline-powered boats. It stays closed unless fuel pump suction opens it. If a break occurs anywhere in the fuel feed line, the valve stops fuel from siphoning out of the tank. Anti-siphon valves are required by Federal law and the USCG on all permanent fuel tank installations.

Key Features:

• Gives Coast Guard and industry-standard anti-siphon protection on gasoline-powered boats
• Meets ABYC H-24 requirements
• Hose barb design combines anti-siphon protection with an easy hose connection
• Brass valves are calibrated for engines of 200 HP and above
• Aluminum valves are calibrated for engines of 200 HP and below
• Available in several barb and NPT thread configurations to match different fuel system layouts

Moeller Marine makes fuel system components for boat builders and boat owners. Choose the brass or aluminum valve that matches your engine's horsepower rating. Use it to build a new fuel system or replace an existing valve, and it will help keep the system compliant and the fuel contained.
