Product Information The Moeller 032550 Permanent Fuel Tank is a large-capacity, marine-grade below-deck fuel tank designed for permanent installation in boats requiring high fuel volume within a long, narrow footprint. Constructed from cross-linked polyethylene (XLPE), the tank provides excellent resistance to corrosion, ethanol-blended fuels, and long-term durability in demanding marine environments.
Engineered to meet modern emissions and safety standards, the tank features a low-permeation design that minimizes fuel vapor loss while maintaining structural integrity. Its extended length and tall profile make it ideal for installations along stringers or in narrow compartments where maximizing capacity is critical. Integrated mounting flanges and molded fittings simplify installation, making the Moeller 032550 a reliable solution for long-range marine fuel systems and custom installations.
