Attwood 8803LP2 is a 3-gallon portable marine fuel tank engineered to meet EPA and CARB regulations and to withstand harsh marine environments. Constructed from UV-grade, automotive-grade multi-layer HDPE materials, this tank resists pressure build-up associated with closed fuel systems and offers additional oil and ullage/vapor capacity. The cap includes an EPA automatic, high-flow vacuum valve so manual venting is not required, and the tank is compatible with 1/4-inch NPT fuel fittings. It complies with ABYC and NMMA requirements for portable marine fuel tanks and is well suited for small outboards. Dimensions: Length 16.6" x Width 11.45" x Height 7.3". No fuel line included.
