Convert Portable Generator to Natural Gas: A Comprehensive Guide
Are you looking to convert your portable generator to run on natural gas? This switch can offer significant benefits, including cost savings, reduced emissions, and increased convenience. In this comprehensive guide, we'll walk you through the process step by step, ensuring you understand each stage and its importance.
Understanding Natural Gas Generators
Before we dive into the conversion process, it's crucial to understand how natural gas generators work. Unlike gasoline or diesel generators, natural gas generators burn a cleaner, more efficient fuel. They're quieter, produce less vibration, and require less maintenance. However, they do require a dedicated gas line for operation.
Why Convert to Natural Gas?
- Cost Savings: Natural gas is often cheaper than gasoline or diesel, leading to long-term savings.
- Reduced Emissions: Natural gas burns cleaner, reducing your carbon footprint.
- Convenience: With a dedicated gas line, you won't need to refuel as often.
Can Your Generator Be Converted?
Not all portable generators can be converted to run on natural gas. Dual-fuel generators, which can already run on both gasoline and propane, are the easiest to convert. Single-fuel gasoline generators may require more extensive modifications. Always check your generator's manual or consult with a professional before proceeding.

Steps to Convert Your Portable Generator to Natural Gas
1. Gather Your Equipment
Before you start, ensure you have all the necessary equipment. This typically includes a natural gas conversion kit, a regulator, gas line fittings, and appropriate tools like a wrench, screwdriver, and pliers.
2. Disconnect the Gasoline System
Start by disconnecting the gasoline system. This involves removing the fuel tank, carburetor, and fuel lines. Be sure to drain any remaining gasoline to avoid contamination.
3. Install the Natural Gas Conversion Kit
Follow the instructions provided with your conversion kit to install the natural gas components. This usually involves installing a gas valve, regulator, and gas lines. Ensure all connections are tight and free of leaks.

4. Connect the Gas Line
Connect your generator to the natural gas line using the appropriate fittings. Ensure the gas line is properly vented to prevent the buildup of dangerous gases.
5. Test the System
Before starting your generator, perform a leak test using a solution of dish soap and water. If bubbles form, you have a leak that needs to be addressed. Once you're confident there are no leaks, you can start your generator.
6. Monitor Your Generator
After starting your generator, monitor it closely. Ensure it's running smoothly and producing the expected power output. Regularly check for leaks and maintain your generator according to the manufacturer's guidelines.
Safety Considerations
Working with natural gas can be dangerous. Always follow these safety guidelines:
- Never attempt to convert your generator if you're not comfortable with the process.
- Always shut off the gas supply before performing any maintenance or repairs.
- Never use a generator indoors, as it can produce deadly carbon monoxide fumes.
- Regularly inspect your gas lines and fittings for leaks or damage.
Conclusion
Converting your portable generator to run on natural gas can offer numerous benefits. However, it's a process that requires careful planning and execution. Always prioritize safety and consult with a professional if you're unsure about any aspect of the process. With the right knowledge and equipment, you can successfully convert your generator and enjoy the many advantages of natural gas power.
