Scepter 12 Gallon Portable Marine Gas Can vs Attwood 6-Gallon Portable Marine Fuel Tank

Overall winner: Attwood 6-Gallon Portable Marine Fuel Tank

Key Differences

Scepter (A) offers a larger 12-gallon capacity and built-in fuel gauge with two-way vented cap, making it better for longer trips and monitoring fuel; Attwood (B) is a smaller 6-gallon tank with an automatic vacuum valve and low-permeation design to reduce evaporation, better for shorter runs and fuel-loss control. A lists a lower price tier and higher capacity; B has a slightly higher average rating and fewer total reviews but some reports of swelling and cap vent issues versus A's reported leakage through the fuel gauge
