Moeller Marine Below Deck Permanent Aluminum Fuel Tank - Available in 20 and 50 Gallon Sizes

The Moeller Marine Below Deck Permanent Aluminum Fuel Tank is built for boat owners who need a durable, code-compliant fuel storage solution that installs beneath the deck or in a dedicated fuel compartment. Constructed from marine-grade aluminum, each tank in this line resists corrosion and pitting from ethanol and biodiesel fuel blends, making it a reliable long-term fit for gasoline or diesel powered vessels. The line spans capacities from 20 to 50 gallons, so whether you are outfitting a center console, cruiser, or larger runabout, there is a size that matches your range and deck footprint requirements.

Every tank ships with a machined aluminum withdrawal fitting featuring a 360 degree swivel poplock, a single fuel pickup, and is compatible with a swing arm sender (A002074) for accurate fuel level monitoring. The aluminum shell carries an 8-rated UV resistance and is rated for operation between 40 and 176 degrees F, holding up in engine compartments and below-deck installations exposed to heat cycling.
