Moeller Marine Below Deck Permanent Fuel Tank, 12 to 25 Gallon

The Moeller Marine Below Deck Permanent Fuel Tank line delivers a rugged, ABYC-compliant fuel storage solution built for permanent installation beneath the deck of runabouts, center consoles, and small cruisers. Rotationally molded from ethanol- and biodiesel-resistant plastic, each tank in this line resists corrosion, pitting, and UV degradation while sealing fill neck and withdrawal/vent fittings directly into the shell to eliminate weak points. Available in 12 gallon and 25 gallon capacities, this line covers everything from compact bow storage to larger below-deck installations, with a machined aluminum withdrawal fitting featuring a 360 degree swivel poplock for flexible hose routing.
