Buying Guide: Key Considerations For Choosing A Natural Gas Conversion Kit
- Generator compatibility: Confirm your model and displacement match the kit’s supported list. Some kits are model-specific, while others claim broader compatibility.
- Fuel flexibility: Decide if you need tri-fuel (gasoline, propane, natural gas) or dual-fuel (gasoline and one alternative). Tri-fuel kits offer more versatility but may be more complex to install.
- Carburetor modification: Look for kits that claim “no permanent modification” for easier reversion or removal, especially if you rely on gasoline.
- Installation effort: Some kits bolt on with minimal tools; others require significant carburetor work. Assess your DIY comfort level.
- Fuel storage and delivery: Consider natural gas availability in your area, installation requirements, and any additional hoses or regulators needed for low-pressure natural gas.
- Reliability in emergencies: Choose kits designed for long-term storage and reduced carburetor gumming, particularly for propane and natural gas use.
- Weight and portability: For small generators, ensure the kit’s added weight and components don’t impede portability or handling.
