<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 033808-10 is a brass anti-siphon valve designed for marine fuel systems on gasoline-powered boats. This critical safety component is required by Federal Law and the United States Coast Guard (USCG) for all permanent fuel tank installations, preventing fuel from siphoning out of the tank in the event of a hose failure or rollover.

Key Features:

  • Brass construction calibrated for outboard engines rated 200 HP and above
  • Coast Guard and industry-standard compliant anti-siphon protection
  • Integrated hose barb design for secure fuel line connection
  • Prevents fuel backflow and potential spills in marine applications
  • Meets federal safety requirements for permanent fuel tank installations

Important: This valve is designed exclusively for marine gasoline fuel systems. NOT to be used in potable water systems. For engines below 200 HP, Moeller offers aluminum anti-siphon valves (model 30 series) specifically calibrated for lower horsepower applications.
