Product Details

The Moeller 033801-10 is a brass anti-siphon valve designed to provide essential fuel system protection on gasoline-powered boats. Anti-siphon valves are required by Federal Law and the United States Coast Guard (USCG) on all permanent fuel tank installations to prevent fuel from siphoning out of the tank in the event of a fuel line rupture or leak.

Key Features:

  • Brass construction for durability and corrosion resistance in marine environments
  • Calibrated for engines rated 200 horsepower and above
  • Delivers Coast Guard and industry standard anti-siphon protection
  • Combines anti-siphon functionality with convenient hose barb design for easy installation
  • Meets federal requirements for permanent fuel tank installations

Important: This valve is designed for marine fuel systems only and is NOT to be used in potable water systems. For engines below 200 horsepower, use the aluminum version (model 033801-30) which is calibrated for lower horsepower applications.

This anti-siphon valve is an essential safety component that helps prevent fuel spillage and environmental contamination while ensuring your boat's fuel system meets all Coast Guard regulations.

Good Pricing.

Good price great quality

Easy to navigate.

My only complaint is that the site couldn't identify the size wheel center caps I needed by vehicle type. I had to measure the center hole on my wheels, lucky I'm a tool junky.

Fine

I registered &amp; was confirmed, but my sign if password doesn't work. Had to use Amazon to get in to shop.

As the merchant name suggests, the process of my purchase was straight forward and simple. I do not need anything else , so next time I will shop here again.<br>Thanks.<br>Julio Gonzalez
