Buying Guide for Auxiliary Fuel Tanks for Generators
Fuel Tank Capacity
Select an auxiliary tank that matches your anticipated runtime needs. Smaller tanks (5-9 gallons) are suitable for short-term or portable use, while larger tanks (12 gallons and above) are better for extended power support. Consider the space available for installation and portability.
Material and Durability
Fuel tanks are commonly made from steel, aluminum, or multi-layer automotive-grade plastic. Steel and aluminum offer tough durability and corrosion resistance, ideal for outdoor or rugged environments. Plastic tanks can be lighter but should be EPA certified for safety and durability.
Compatibility and Mounting
Ensure the tank’s dimensions and mounting holes align with your generator or support setup. Brand-specific tanks provide tailor-made fit and often come with necessary hardware, whereas universal tanks require inspection of size and mounting methods for compatibility.
Ventilation and Safety Features
Look for tanks with built-in vent valves or vacuum-release caps to prevent pressure buildup during use. EPA and CARB certifications indicate compliance with environmental and safety standards. Tanks without vent valves may need additional accessories to ensure safe fuel flow.
Included Accessories
Some fuel tanks come with fuel petcocks, fuel lines, gaskets, and mounting hardware included, which can simplify installation. Verify these inclusions to avoid purchasing additional parts separately.
Fuel Gauge and Monitoring
Fuel tanks with built-in gauges allow you to easily monitor fuel levels without opening the tank, adding convenience and preventing spills.
Application and Usage
Consider whether the tank is intended for use with specific generator models, lawn tractors, or universal applications. Brand-specific auxiliary tanks ensure perfect fit and function, while universal tanks are more versatile but require compatibility checks.
