Product Information The Moeller 032640 Permanent Fuel Tank is a high-capacity, marine-grade below-deck fuel tank designed for permanent installation in boats requiring substantial fuel storage with a compact footprint. Constructed from cross-linked polyethylene (XLPE), the tank offers excellent resistance to corrosion, ethanol-blended fuels, and long-term durability in harsh 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 tall, wide-profile design allows for increased fuel capacity in installations where vertical clearance is available, making it ideal for larger vessels or extended-range applications. Integrated mounting flanges and molded fittings simplify installation, ensuring dependable performance in marine fuel systems.
