RotopaX 4 Gallon Gasoline Fuel Pack

Key Features

• 4.0 US gallon capacity — the largest fuel pack in the RotopaX lineup for maximum reserve fuel on expedition and long-range builds
• Slim 3-inch depth profile matches the 1 and 2 gallon packs, running longer rather than wider to achieve added capacity
• Roto-molded construction with thicker walls and reinforced handles for extreme durability
• Sure-seal gasket keeps the spout leak-proof and vibration-resistant on rough terrain
• Patented three-layer roto-molding process with specialty barrier material — EPA and CARB 50-state compliant
• Compatible with all RotopaX mounting systems — Standard, DLX, and LOX pack mounts (sold separately)
• Stackable using the 1, 2, and 4 Gallon Extension to add capacity on a single mount setup (sold separately)
• ECO/CARB-style spout included — requires light pressure to dispense, reducing accidental spills
• Spout stores inside the container when not in use
• Colorfast red construction helps distinguish it from water and diesel packs at a glance
• 10-year leak-free warranty
• Made in the USA
