Buying Guide: Key Considerations For Choosing A Natural Gas Conversion Kit
- Compatibility: Verify that the kit matches your generator model or a broad range of models. Some kits are designed for specific units, while others claim multi-model compatibility.
- Fuel options: Decide whether you want true tri-fuel capability (gas, propane, natural gas) or a focused natural gas option with gasoline back-up. Tri-fuel options offer maximum flexibility during outages or travel.
- Installation: Look for kits that require minimal permanent modification. Reversible modifications preserve resale value and ease serviceability.
- Safety and certification: Check for high-quality materials (brass fittings, corrosion resistance) and any CSA or other safety certifications. Ensure that hose and fittings meet local codes and standards.
- Maintenance: Consider components designed to reduce carburetor gum buildup and ethanol-related issues. Cleaner-burning fuels may reduce maintenance needs over time.
- Portability and length: If you use outdoor setups or RVs, hose length (like 24 feet) and connector versatility can influence placement and usability.
- Clear labeling and instructions: Proper documentation reduces installation errors and helps users switch fuels safely.
