Look for a natural gas conversion kit for a generator designed specifically for your generator model and the desired fuel type. Conversion kits are available for various fuel types including propane natural gas and biogas. Ensure that the kit matches your generator’s make and model.


3. Gather the Necessary Tools


Review the conversion kit instructions and gather the tools needed for the conversion process. The kit instructions should provide a list of required tools and any additional equipment needed.


4. Prepare the Generator


Make sure the generator is unplugged from all power sources and switched off. Before proceeding, let it totally cool down.


5. Install Dual Fuel Conversion Kit


Follow the instructions provided with the duel fuel conversion kit to install the necessary components. This typically involves replacing the carburetor, adjusting fuel jets, and installing a regulator or other elements specific to the fuel type.


6. Connecting the Natural Gas Supply


After installing the converter components, connect the natural gas supply line to the generator. Ensure the fittings and connections are correct and the gas supply is adjusted for the generator’s needs.


7. Adjust the Settings


Once the conversion kit is installed, you may need to adjust various settings to ensure proper fuel flow and optimize performance. These adjustments may include the air-fuel mixture, pressure settings, or other parameters specific to your generator and conversion kit.


8. Test and Fine Tune


After the conversion, start the generator and observe its operation. Check for any fuel leaks, unusual noises, or performance issues. Make any necessary adjustments as per the conversion kit instructions or consult a professional technician if you encounter difficulties.

Remember, gas-related tasks can be hazardous, so it’s strongly recommended to seek professional assistance to ensure the conversion is done safely and correctly.

How to Convert Natural Gas Without a Conversion Kit?


Converting a portable generator to run on natural gas without a conversion kit is not recommended. Converting a generator’s fuel source requires specific components and adjustments to ensure safe and efficient operation. Without a proper conversion kit, it is difficult to make the necessary modifications correctly.

However, if you still want to proceed without a conversion kit. Keep in mind that this is not recommended and could lead to safety hazards or damage to the generator:

Consult the manufacturer: Before attempting any modifications, research your generator model and consult the manufacturer’s documentation or website. They may provide specific instructions or guidelines for conversions, although it is unlikely they will support converting without a conversion kit.

Need this

  • Two feet of copper pipe
  • Drill machine
  • Cutting plier
  • Natural gas regulator

Modify the carburetor: Similar to using a conversion kit, the process begins by opening the air filter box and removing the filter. then remove the carburetor from the engine. open the carburetor bold.

Then drill a hole in the carburetor. this is the right way and then fit the copper pipe in the carburetor hole. this process is risky in case of damage to the carburetor airline,

natural gas regulator Install a natural gas regulator: Natural gas requires specific pressure regulation, so you would need to install a natural gas regulator in the fuel supply line to control the pressure and ensure safe operation.

Make the adjustments: After modifying the carburetor and installing the regulator, you may need to fine-tune various settings, such as the air-fuel mixture and pressure levels, to ensure optimal performance.

Please note that converting a generator to run on natural gas without a conversion kit can be hazardous and may void any warranties. It is strongly recommended to consult the manufacturer or a professional technician before attempting any modifications.


Benefits of Running a Portable Generator on Natural Gas


Operating a portable generator on natural gas offers several benefits to consider. Let’s explore some of the benefits associated with using natural gas as a fuel source.

Profitability: Natural gas is often more profitable than gasoline or diesel. Its price stability and availability could make it a more affordable long-term fuel option.

Environmental benefits: Natural gas burns cleaner than gasoline or diesel helping to reduce emissions of harmful pollutants. It produces less carbon nitrous oxide and particulate emissions which improves air quality.

Convenience and availability: Natural gas is widely supplied through pipelines in many areas. This accessibility makes refueling easier and more convenient than transporting and storing gasoline or diesel.

Longer Run Time: Natural gas typically provides longer runtimes than gasoline or diesel. This can be useful during prolonged outages or when longer power-up times are required.

Reduced maintenance: Natural gas burns cleaner, produces fewer carbon deposits, and less engine wear. This can reduce maintenance requirements and prolong engine life.


Disadvantages of Natural Gas-Powered Portable Generator


Despite the notable benefits, it is important to consider the limitations and challenges associated with using portable natural gas generators. Some of the main disadvantages include:

Conversion Process: Converting a portable generator to running on natural gas requires time, effort, and technical knowledge. It may not be a simple process for everyone, and incorrect conversions can lead to performance issues or security risks.

Limited Compatibility: Not all portable generators are compatible with natural gas conversion kits. It is essential to ensure that the generator model you own or plan to purchase can be successfully converted to run on natural gas.

Fuel storage: Unlike gasoline or diesel, which can be stored in portable containers, natural gas requires a dedicated supply line or connection. This means you must have access to natural gas or the right infrastructure to store and transport the fuel.

Reduced Mobility: Using a portable natural gas generator may limit its portability as it requires a permanent connection to a natural gas source. This can be a drawback in situations where portability is a priority.
