The other day I converted a Honda Eu2000 into a tri fuel generator. Now this is the second time, I have converted one and I am no mechanic, if I can do it anyone can. Now a tri fuel generator runs on gasoline, propane and natural gas. Natural gas may be available for a period of time after electricity fails. Propane stores indefinitely and gasoline may be available at times. With the ability to run on all three fuels you have a better chance of finding fuel in an emergency.
The Honda Eu2000i tri-fuel kit that I installed came from Century Fuel Products . This company manufactures a wide range of adapters that sell from $199 and up. Most generators can be converted for the minimum price and there is free shipping on most orders.
There are two main types of conversion units currently on the market that I am aware off. The one requires you to change your carburetor. The one manufactured by Century Fuel Products is an adapter that uses your current carburetor. An adapter will mix the Propane or Natural Gas into the air stream before the gasoline carburetor. The adapter was surprisingly easy to install. The hardest part was installing a shut off valve on the fuel line. They provided the extra fuel line hose needed to install the valve and it is good quality. You have to work a bit to get it onto the fittings. The rest was a piece of cake.
I really liked the way in which the regulator was attached. It was mounted on a metal bracket that attaches to the feet on the bottom of the generator. Some other brands attach theirs to the plastic body, which I am afraid might weaken over time.
Once the unit was installed we connected a propane tank to the tri fuel generator, primed the unit with the button on the back of the regulator and it started on the second pull. At first, it ran a bit rough, but then we found out that there are two adjustments on the regulator. One adjusts sensitivity and the other adjusts the needle valve. While the instructions were excellent on the whole, they did fail to mention the two adjustments on the regulator. It took a single phone call to the manufacturer to find out about them. They stated that in the future they will redo their instructions to include this information.
If I have any criticism, it would be that the cover does not fit quite flush with the body after you install the adapter. But I can live with this. Based on my experience I can recommend Century Fuel Products.
Personally, I will run my tri fuel generator on propane or natural gas as much as possible. You do not get gummy residue in the carburetor and it eliminates the worry about the carburetor being clogged up from old fuel.
