AltFuel Propane Conversion kits

AltFuel Propane conversion kits for small engines


AltFuel is dedicated to providing safe, effective, cost efficient and easy to install propane conversion kits for small (4 cycle) gasoline engines. We are manufacturing units in the United States, creating new jobs and utilizing domestically refined propane. Propane fuel decreases our country’s dependence on foreign oil while reducing fossil fuel pollution which protects the environment.


AltFuel LLC was founded in 2009 to manufacture propane conversion kits that allow the use of a cleaner alternative fuel to power small 4 stroke carbureted gasoline engines. We have engineered a simple and safe system to easily convert existing equipment to propane while maintaining usability and performance. Our Green Conversion Kit will convert most gasoline engines 1-45 HP to operate on propane vapor fuel, which is the most viable alternative to gasoline available at this time.

Our unique system saves money by using less expensive propane and making equipment more efficient with less wear and tear and maintenance. Small engines running on our propane conversion systems have been proven to have 80% cleaner emissions and help the engine last longer than those operating on gasoline.

The AltFuel Conversion Kit is offered in two adaptive models. After determining the correct model for the engine being converted, the appropriate fuel supply line and intake adapter plate is chosen to complete the conversion with the addition of a propane tank of suitable size.

To follow are the components needed to convert your small engine to clean, safe propane.
