FUEL TANK, BELOW DECK 13 GAL

Moeller 032513 Permanent Fuel Tank

The Moeller 032513 Permanent Fuel Tank is a compact, elongated marine fuel tank designed for permanent below-deck installation in boats where narrow or irregular spaces require a slim profile. Constructed from cross-linked polyethylene (XLPE), the tank provides excellent resistance to corrosion, ethanol-blended fuels, and long-term environmental exposure in demanding marine conditions.

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 long, narrow footprint makes it ideal for installations along stringers or in tight compartments where wider tanks cannot fit. Integrated mounting flanges and molded fittings simplify installation, making the Moeller 032513 a reliable solution for both new builds and retrofit fuel systems.
