Introduction
Portable generators are essential tools for backup power, job sites, outdoor events, and remote locations. However, most generators leave the factory configured to run on gasoline only. While gasoline is convenient, it has limitations such as shorter shelf life, higher emissions, and supply disruptions during emergencies. For generator owners seeking flexibility, fuel efficiency, and long-term reliability, fuel conversion kits provide a practical solution.
The Impco Tri-Fuel Propane Natural Conversion Generator EB6500 GX389 kit is designed to convert compatible generators to operate on gasoline, propane, or natural gas. Built by Impco, a recognized manufacturer of alternative fuel systems, this conversion kit allows users to choose the most available or cost-effective fuel source without sacrificing generator performance.
In this detailed Impco Tri-Fuel Conversion Kit review, we explore its design, compatibility, installation considerations, performance characteristics, and long-term value. All specifications and product details are based on accurate data sourced from Amazon listings and manufacturer-provided information.

Although the listed item weight is minimal, this reflects the individual component weight rather than the full installed system. Once installed, the kit forms a robust fuel delivery assembly designed for long-term use.
Installation Considerations
Installing a tri-fuel conversion kit requires mechanical knowledge and attention to detail. While the Impco Tri-Fuel Conversion Kit is designed for precise fitment, installation typically involves:
- Removing or modifying the existing carburetor setup
- Mounting the fuel mixer using the flange mount
- Connecting propane and natural gas supply lines
- Adjusting fuel mixture for optimal performance
Professional installation is recommended for users unfamiliar with fuel systems, especially when connecting to natural gas lines.
Performance on Different Fuel Types
One of the most important considerations with tri-fuel generators is performance variation across fuel types.
Gasoline Operation
Gasoline provides the highest power output and is ideal for applications requiring maximum wattage. Performance remains close to factory specifications when using gasoline.
Propane Operation
Propane burns cleaner than gasoline and produces fewer emissions. While power output may be slightly reduced, propane offers consistent performance and long-term fuel storage benefits.
Natural Gas Operation
Natural gas provides unmatched convenience through continuous supply. Power output is typically slightly lower than gasoline, but reliability and runtime are excellent for standby use.
Fuel Efficiency and Emissions
Tri-fuel systems offer improved emissions performance, particularly when operating on propane or natural gas. These fuels produce fewer carbon deposits, which can contribute to longer engine life and reduced maintenance requirements.
Fuel efficiency varies by application, but many users appreciate the reduced odor and cleaner exhaust associated with alternative fuels.
Safety Considerations
Safety is a key factor when working with multiple fuel types. Proper installation and ventilation are essential. The Impco Tri-Fuel Conversion Kit is designed to integrate safely when installed according to manufacturer guidelines.
Key safety considerations include:
- Secure fuel line connections
- Proper ventilation during operation
- Use of approved regulators and hoses
- Compliance with local codes for natural gas connections
Following best practices ensures safe and reliable generator operation.
Use Cases and Practical Applications
The Impco Tri-Fuel Conversion Kit EB6500 GX389 is suitable for a wide range of applications.
Home Backup Power
During extended outages, fuel flexibility allows homeowners to continue operating essential appliances even if gasoline supplies are limited.
Job Sites
Contractors benefit from the ability to use propane for cleaner operation in sensitive environments or gasoline for maximum output.
Emergency Preparedness
Preparedness-focused users value the redundancy of multiple fuel options during disasters or supply disruptions.
Remote Locations
Natural gas operation is ideal for locations with utility access, providing continuous power without refueling.
Comparison With Single-Fuel Generators
Converting a generator to tri-fuel operation provides advantages over single-fuel configurations.
| Feature | Single-Fuel Generator | Tri-Fuel Conversion |
|---|---|---|
| Fuel Flexibility | Limited | High |
| Emergency Readiness | Moderate | Excellent |
| Emissions | Higher | Lower on propane/natural gas |
| Runtime Options | Restricted | Expanded |
This comparison highlights the versatility gained through conversion.
Maintenance and Long-Term Reliability
Generators converted with tri-fuel systems often experience reduced carbon buildup when operating on propane or natural gas. This can lead to:
