Bergs System HND1.2000IS Bergs Single System W/Tank Hose
The Bergs HND1.2000IS is a single-system setup that includes a tank hose designed to extend generator runtime. It is built as a compact, integrated solution for users seeking a straightforward extension without extensive modification to their current configuration. The package is labeled as a Bergs single system with an included tank hose, Model#: HND1.2000IS, facilitating a simpler upgrade path for compatible generators.
Hihitomorrow HND1.2CS Clam Kit
The Hihitomorrow HND1.2CS kit is a single system clam-style extension designed to work with Honda EU1000i and EU2000i generators. It can extend runtime by providing a separate fuel-handling path without altering the OEM cap, making it a non-invasive upgrade. The package includes essential components: a gas tank cap, fuel hose, elbow fitting, teflon tape, and a female coupler, totaling five pieces for a complete assembly.
Attwood 8806LP2 Portable Fuel Tank
Attwood’s 8806LP2 is a 6-gallon portable fuel tank designed for marine use with EPA and CARB compliance. The tank features a built-in vacuum valve in the cap, eliminating the need for manual venting. This solution provides a reliable, compliant option for users needing extended fuel capacity for boats or generators used in marine environments, with emphasis on safety and regulatory adherence.
Scepter 08669 Rectangular 12 Gallon Tank
The Scepter 08669 is a low-profile rectangular 12-gallon marine fuel tank suitable for longer outings. It features a 2-way vented gas can cap to regulate airflow and prevent vapor buildup, and includes a built-in fuel gauge for quick level checks. The tank is compatible with standard 1/4 NPT marine fittings, making it a practical option for extended-range setups where space is a factor.
YOOWEE HND1.2CS Extended Fuel Kit
The YOOWEE HND1.2CS is an extended fuel kit designed for EU1000i and EU2000i generators, replacing the standard HND1.2CS clam kit to extend runtime. Note that the generator and fuel tank are not included in this kit. The kit helps to extend runtime by providing an integrated approach to fuel supply, while maintaining compatibility with existing EU-series models.
Buying Guide: Key Considerations For Extended Fuel Tanks
Choosing the right extended fuel tank setup involves evaluating compatibility, capacity, and practical installation considerations. Here is a concise guide to help you compare options and choose the best solution for your needs.
- Compatibility: Verify generator model compatibility before purchasing. Look for kits explicitly listed for your model, such as EU1000i, EU2000i, EU2200i, or other supported units. Some kits are brand-specific, while others offer broader compatibility with multiple brands.
- Capacity vs. Space: Consider how much extra runtime you need and how much physical space you have. Larger tanks provide longer runtimes but require more storage area and may add weight. Evaluate the balance between capacity and portability.
- System Type: Decide between a single-system, dual-system, or clam-style kit. Single-system kits are typically easier to install, while dual-system kits can feed multiple generators from a single extended tank, useful for multi-generator setups.
- Safety and Regulations: For marine or sanctioned environments, ensure compliance with EPA/CARB standards and use components designed for the environment (marine-grade materials, vented caps, etc.).
- installation effort: Some kits are straightforward plug-and-play with minimal modifications, while others require accessory hoses, fittings, or sealing materials. Review included parts lists to foresee any extra hardware you may need.
- Materials and Durability: Look for anodized aluminum, brass fittings, and robust hoses when extended use is expected. Durable components translate to longer service life under frequent refueling or transport conditions.
- Maintenance and Gauging: If your setup includes a built-in gauge, confirm accuracy and ease of fuel level monitoring. Regular checks help prevent running out mid-use and reduce downtime.
- Cost vs. Benefit: Compare the incremental cost of the extended tank against the expected runtime gain. If you frequently operate generators away from refueling options, the investment often pays off in reliability.
Across these options, users should weigh how the extended fuel tank integrates with their existing setup, whether for recreational boating, remote job sites, or emergency power backup. Each product emphasizes safe operation, regulatory compliance where relevant, and practical extensions to standard fuel capacities.
