<h3>Moeller Marine Products: The Industry Standard in Marine Fuel Systems</h3><p>When it comes to outfitting a boat with dependable, safety-focused equipment, few names carry as much weight as <strong>Moeller Marine Products</strong>. With more than 25 years of engineering experience behind every product, Moeller has earned its reputation as the premier fuel system manufacturer in the marine industry — trusted by both production boat builders and weekend anglers alike.</p><p>At the heart of Moeller's business is fuel containment. As one of the largest rotational molders in the marine industry, Moeller engineers and manufactures its tanks using advanced crosslink polyethylene construction that is designed to resist corrosion, withstand the rigors of marine environments, and remain compatible with ethanol-blended fuels. Their lineup spans the full spectrum of fuel storage needs: <a href="/7465-moeller-portabletopside-tanks-200799">portable and topside fuel tanks</a> for center console, pontoon, deck, and jon boat applications are EPA-certified and ready to install right out of the box, while their permanent below-deck models — available in 42 configurations ranging from 12 to 150 gallons — give custom boat builders the flexibility to spec the right solution for virtually any hull design.</p><p>But Moeller's expertise extends well beyond fuel tanks. Anglers will find Moeller's line of <a href="/7465-moeller-bait-tanks-200125">bait tanks and livewells</a> invaluable for keeping catches alive and healthy on the water. These above-deck and portable livewell systems are engineered with the same attention to durability and functionality that defines every Moeller product, making them a natural choice for serious fishermen who demand reliable performance on every trip.</p><p>Moeller also addresses one of the most overlooked essentials in boat outfitting: battery management. Their <a href="/7465-moeller-battery-boxes-trays-200139">battery boxes and trays</a> are purpose-built to safely secure marine batteries against the constant vibration and moisture exposure of on-water use, helping to protect your electrical investment and keep your boat's systems running reliably.</p><p>Rounding out their catalog, Moeller offers a comprehensive suite of fuel accessories — including connectors, valves, fuel line assemblies, water separator/filters, fuel senders and gauges, vents, and hold-downs — so boaters can build or service a complete, code-compliant fuel system from a single trusted source. From OEM boat builders speccing out new models to do-it-yourself boaters replacing aging components, Moeller provides the products and engineering resources to get the job done right.</p><h3>Why Boaters Trust Moeller</h3><ul style="list-style:disc"><li><strong>25+ years</strong> of marine fuel system engineering and manufacturing expertise</li><li>Among the <strong>largest rotational molders</strong> in the marine industry nationwide</li><li>Tanks engineered for <strong>ethanol-blended fuel compatibility</strong> and long-term durability</li><li><strong>EPA-certified</strong> topside tank designs for regulatory peace of mind</li><li>A complete ecosystem of <strong>fuel accessories</strong>, livewells, battery accessories, and more</li><li>Products serving both <strong>OEM builders</strong> and aftermarket boating enthusiasts</li></ul>

Product Details

The Moeller 033802-10 is a marine-grade anti-siphon valve designed to prevent fuel siphoning in permanent fuel tank installations. Required by Federal Law and the U.S. Coast Guard for all gasoline-powered boats, this valve provides essential safety protection against fuel backflow and siphoning.

Key Features:

  • USCG-approved anti-siphon protection for gasoline marine fuel systems
  • Integrated hose barb design for secure fuel line connections
  • Calibrated for use with outboard engines rated below 200 horsepower
  • Aluminum construction for corrosion resistance in marine environments
  • Prevents fuel from siphoning back through the fuel line when engine is off
  • Complies with federal regulations for permanent fuel tank installations

This anti-siphon valve is an essential safety component for any permanent marine fuel system. It installs inline in the fuel system between the tank and engine, automatically preventing fuel from flowing backward through the lines. Not approved for potable water systems.
