YOOWEE Single System Clam Kit HND1.2CS Extended Fuel Kit
The YOOWEE Single System Clam Kit HND1.2CS is designed to increase the runtime of Honda EU1000i and EU2000i generators by allowing connection to an extended external fuel tank. It replaces the original HND1.2CS clam kit, offering the convenience of extended operation without frequent monitoring or refueling. This kit itself does not include the external tank but equips your generator to connect seamlessly to one.
Its main function is to provide fuel continuously from an external source, so you avoid interruptions during use. Compatible only with specific Honda models, it’s an efficient way to maintain power output during extended operations like camping, job sites, and emergency use.
maXpeedingrods 12V DC Gasoline Electric Fuel Pump
The maXpeedingrods 12V DC Gasoline Electric Fuel Pump is a smart, automated accessory that increases generator runtime by pumping fuel from an external tank to the generator without stopping it. It features an automatic fuel level sensor that stops pumping when the generator’s tank is full, preventing leaks and overflow.
This unit is useful for continuous operation setups requiring longer runtimes without manual refueling interruptions. It supports quick connect ports for easy tank attachment and operates with a single click to start monitoring fuel flow. Note that this pump requires a separate fuel tank purchased independently, making it a versatile choice for custom extended fuel solutions.
Attwood 8806LP2 EPA Certified 6 Gallon Portable Fuel Tank
Attwood’s 6 Gallon Portable Fuel Tank offers a reliable external fuel storage solution compliant with EPA and California air resources board regulations. While designed primarily for marine applications, this tank is an excellent choice for generator fueling needs requiring portability and regulatory compliance.
It includes a cap with a built-in vacuum valve, eliminating the need for manual venting during fuel transfer. The tank’s durable construction is suitable for harsh conditions, making it a practical option for outdoor use with your generator setup.
HND1.2CD Dual System Extended Run Generator Fuel Kit
The HND1.2CD Dual System Extended Run Generator Fuel Kit from sixcow supports multiple popular brands, including Honda EU series, Generac, Champion, Kipor, and Polaris. Unlike single system kits, this dual setup allows one extended fuel tank to feed two generators simultaneously, extending power output and reducing refueling interruptions.
Constructed with aircraft-grade anodized aluminum caps and durable rubber hoses, this kit promises corrosion resistance and wear durability, suitable for prolonged outdoor use. It’s ideal for users with multiple generator units looking to streamline fuel management while maintaining continuous operation during power outages or extended use.
Z-GS-0795-AP Replacement Fuel Tank for DeVilbiss and Excell Generators
This Z-GS-0795-AP Replacement Fuel Tank is designed specifically for DeVilbiss and Porter Cable generators, providing a new-style extended run fuel tank for models needing an improved external fuel source. It includes an access hole on the tank top, reinforced walls, and a zippered seal for durability and better mounting.
The kit comes complete with mounting hardware and hardened components such as a Viton grommet and fuel tank petcock, easing installation and enhancing longevity. This tank replacement kit is a brand-specific solution for owners wanting to upgrade or extend their generator’s fuel capacity without compatibility issues.
Buying Guide For Extended Fuel Tanks For Generators
Compatibility With Generator Model
Check if the extended fuel tank or kit is compatible with your specific generator make and model. Many options are designed for Honda EU series, Generac, or brand-specific generators, so matching the kit avoids installation and operational issues.
Fuel Capacity And Runtime Extension
The size of the external fuel tank directly affects runtime extension. Consider your power usage needs to select between 5-gallon, 6-gallon, or larger tanks. Some kits offer dual-system support to power multiple generators at once.
Material Quality And Durability
Look for tanks made from corrosion-resistant metals like anodized aluminum or robust plastics such as high-density polyethylene. Quality tubing and valves ensure leak-free fuel delivery and long-lasting performance in outdoor conditions.
Ease Of Installation And Operation
Kits that plug directly into your generator’s fuel system or offer quick-connect fuel ports simplify setup. Automated fuel pumps with level sensors can manage fuel flow without manual intervention, allowing for continuous runtime without shutdowns.
Environmental Compliance
Ensure the fuel tank meets EPA or CARB regulations if local laws require. Built-in vacuum valves or venting features are also important to prevent vapor lock and fuel spillage during use.
Additional Accessories And Hardware
Some extended fuel tank kits come with mounting hardware, fuel lines, grommets, and fuel petcocks included. Verify what accessories are supplied to avoid needing extra parts for a complete setup.
Portability And Storage Considerations
Depending on usage scenarios, you may prefer portable tanks with easy carrying handles or fixed external tanks for stationary setups. Durable construction that resists impacts and environmental damage is essential for outdoor applications.
