Moeller Portable/Topside Tanks

When it comes to marine fuel containment, Moeller has established itself as an engineering leader in the portable and topside tank category. With more than 25 years of engineering experience, quality processes, and manufacturing know-how, Moeller delivers fuel storage solutions that address the unique challenges faced by recreational boaters and professional mariners alike.

Advanced Material Science for Maximum Protection

What sets Moeller apart in the portable and topside tank market is their commitment to advanced materials engineering. Moeller manufactures portable tanks from nano-particle–infused high density polyethylene to prevent the escape of hydrocarbons at the molecular level. This sophisticated construction method goes beyond traditional HDPE manufacturing, creating a barrier that meets stringent environmental standards while ensuring long-term durability in harsh marine conditions. The tanks are manufactured from high-density multi-layer polyethylene with ultraviolet inhibitors, protecting against the sun's damaging rays during extended exposure on deck.

Comprehensive Product Range for Every Application

Moeller offers both portable tanks (12 gallons and under per EPA definition) and larger topside models to accommodate various vessel types. Their line of topside tanks offers an EPA-certified, low-cost solution for center console, pontoon, deck, and jon boat designs. The product lineup includes specialized configurations like low-profile models for space-constrained installations, high-profile versions for easier filling, and bow tanks designed to fit in tight compartments of inflatables and dinghies.

Each tank comes equipped with practical features that matter on the water: 360-degree rotating withdrawal elbows for flexible fuel line routing, mechanical direct sight gauges for accurate fuel monitoring, and mechanically vented caps that float if dropped overboard. The Gas Walker portable fuel transport system provides a convenient solution for carrying fuel to remote locations, complete with integrated hose, aluminum nozzle, and brass shutoff valve.

Regulatory Compliance and Ethanol Compatibility

All tanks meet the new "low permeation" standards in place by the EPA/CARB regulations, and all portable tanks 12 gallon and under meet current USCG and ABYC Standards. This compliance ensures that Moeller portable and topside tanks can be used confidently across all U.S. waterways. Importantly, these tanks are engineered to handle today's ethanol-blended fuels without degradation, a critical consideration as E10 and higher ethanol content fuels become standard.

Whether you're outfitting a small fishing skiff, replacing an aging fuel system on a center console, or building a custom pontoon boat, Moeller's portable and topside tanks deliver the combination of regulatory compliance, material innovation, and practical design features that serious boaters demand from their fuel containment systems.
