Attwood EPA and CARB Certified 6-Gallon Portable Marine Tank
Attwood’s portable 6-gallon tank is EPA and CARB certified, with a cap featuring a built-in vacuum valve to minimize venting. While marketed for marine use, it offers a compliant, larger-capacity fuel container option for generators when used with compatible fittings and transfer hoses. Best for users who prioritize regulatory compliance and larger fuel capacity for extended outdoor operations. Caution: marine-focused design may require adapters for non-marine applications.
Buying Guide: How to Choose an Extended Gas Tank System for Generators
- Compatibility: Confirm that the fuel extension system works with your generator’s exact model and any required clam kit or tank hoses. Some kits are model-specific (for example, EU1000i/EU2000i), while others offer broader compatibility.
- Capacity and runtime: Evaluate how much extra run time the system provides and whether that aligns with your typical usage pattern—camping trips, job sites, or backup power during outages.
- Durability and materials: Look at construction materials (steel, brass, aluminum alloy, rubber) and the build quality, especially for outdoor or rugged environments.
- Installation effort: Consider how easy or difficult the kit is to install. Some require only hose and cap replacements, while others need more extensive setup or professional installation.
- Regulatory and safety: If using in a marine context or near regulated environments, ensure any fuel systems meet local emissions and safety standards. Venting valves and secure caps reduce spill and vapor risks.
- Portability vs. permanence: Decide if you want a portable external tank (like marine tanks) or a semi-permanent inline system that integrates with the generator’s fuel line.
- Maintenance: Check for parts availability (gaskets, hoses, caps) and ease of maintenance. Replacement parts are important for long-term reliability.
FAQ
- Q: Will an extended gas tank work with all generator brands?
A: Not universally. Most extended systems target specific models or families (like Honda EU1000i/EU2000i). Verify compatibility with your generator before buying. - Q: Do these kits require professional installation?
A: Some installations are straightforward for DIY enthusiasts, while others may require basic knowledge of fuel systems. Check the kit instructions for installation requirements. - Q: Can I use a marine-grade tank for a home backup generator?
A: A marine tank can be adapted for use with a generator, but ensure compatibility with fittings, hoses, and local regulations. Some marine tanks include compliant venting and caps. - Q: Will the extended system change my generator’s warranty?
A: It depends on the manufacturer’s policy. Some aftermarket kits are designed to be non-intrusive, while others may affect warranties if modifications are involved. Always verify with the generator’s maker. - Q: How do I know if the fuel hose and fittings are safe for prolonged use?
A: Look for components made of durable materials (steel, brass, aluminum alloys, rubber) and check for corrosion resistance and compatibility with gasoline or the intended fuel type. - Q: Is there a recommended maintenance schedule for extended fuel systems?
A: Regular inspection of hoses, caps, and fittings for leaks or wear is advised. Replace worn parts promptly to maintain safety and performance.
