Attwood 8803LP2 3-Gallon Portable Marine Fuel Tank - EPA/CARB

In this review of the Attwood 8803LP2, the bottom line is simple: this is a compact, regulation-compliant portable fuel tank best suited for small boats and those who need a dependable, ready-to-go tank that meets strict emissions rules. The reviewer found the tank's EPA and CARB certification and automotive-grade, multi-layer construction to be the single biggest reasons to buy, since they offer regulatory compliance and durable build quality in one compact package.

Key Features

• Multi-layer construction: Automotive-grade layers resist pressure build-up in closed fuel systems, helping the tank maintain structural integrity under use.
• Built-in vacuum valve cap: The cap includes a vacuum valve so users do not need to manually vent the tank during normal operation.
• Regulatory compliance: The tank meets EPA and CARB standards, which ensures it is suitable for use where strict emissions rules apply.
• ABYC/NMMA compatibility: Compliance with ABYC and NMMA requirements means the tank fits standard portable marine needs and works with common boat setups.
• Compact 3-gallon capacity: The small size provides portability and easy stowage for small craft, tender boats, and hunting skiffs.

Who It's For

The Attwood 8803LP2 is aimed at owners of small runabouts, jon boats, inflatable tenders, and duck hunting boats who need a portable, regulation-compliant fuel solution that is easy to carry and store. Its 3-gallon capacity and compact footprint make it practical for day trips and short outings where space and weight matter.

Boat owners who regularly run long distances, need larger reserve capacity, or who operate in extreme heat without close monitoring should consider larger or differently vented options, since some customers report swelling and minor venting concerns in hot conditions.
