Buying Guide for Extended Fuel Tanks for Generators
Choosing the right extended fuel tank or kit for your generator is essential to maximize fuel efficiency and runtime. Below are key factors to consider before purchasing:
Compatibility
- Model Specific or Universal: Some tanks and kits are designed for particular generator brands like Honda, DeVilbiss, or Predator and will guarantee fit and proper function.
- Dimensions and Mounting Points: Ensure the replacement tank matches your generator’s mounting holes and space to avoid installation issues.
Fuel Capacity
- Runtime Needs: Larger tanks provide longer runtimes but may be bulkier and heavier.
- Actual vs. Stated Capacity: Some tanks may have a labeled capacity (e.g., 7 gallons) but might hold slightly less actual fuel.
Ventilation and Safety Features
- Vent Valves: Vent valves prevent vacuum lock but not all tanks come with this feature, affecting fuel flow reliability.
- Material Quality: Choose tanks made from durable and fuel-resistant materials like steel or reinforced plastic.
Fuel Transfer Mechanism
- Fuel Pumps or Clam Kits: Some products include automatic fuel pumps or clam kits to enable continuous fuel feed without stopping the generator.
- Ease of Connection: Look for quick-connect fittings or easy installation hardware to simplify setup and maintenance.
Regulatory Compliance
- Emission Standards: Tanks certified by EPA or CARB ensure safer environmental performance and compliance with regulations.
Considering these aspects ensures you select an extended fuel tank or kit that fits your generator, extends runtime efficiently, and provides safe and reliable operation.
