Default Has anyone converted their gasoline generator to natural gas?

I have a 5000w Honda gasoline generator that I think I want to convert to natural gas.

I saw this conversion kit on eBay, and wondered if anyone has used it, knew someone that has, or has any other input about converting the generator to natural gas.

This kit states that it can be used with 3 types of fuel...gasoline, nat. gas, and propane.

In hurricane situations, gasoline is easier to get and store than gas. Do you have nat gas through a utility where you plan to use it? Will that system stay up during/after a storm?

City gas to the house

The kit states that it will use gasoline, propane, or natural gas......with no other modifications.

Here where I live my generator runs on Propane the nice thing is the Propane companies use trucks that run on Propane so never worry about a delivery,

switching to Nat gas or propane will de-rate the genny, maybe 20%?
someone else may have a more accurate figure.
Not as much energy per measure.
Multi fuel may add versatility though.

I've converted both my Honda i2000 generators to natural gas. I sent the carb out on one, and did the other myself.

I did not use the product you see on ebay. It contains many of the same things I use and you will need the regulator and the thumb screw device on either upgrade.

I had a plumber add a extention on my home natural gas line. On the end is a T and at the end of each T is the regulator. Then I have some hose (like you use for your barbeque) that goes to a simple brass lever valve I use to dial down the gas flow to the appropriate amount. Then theres a line that dumps into the top of my carb. Drilling the appropriate size hole in the proper location and then epoxying it in place was the tricky part.

My generators work great on natural gas. Takes about three or four pulls to draw natural gas into the carb before the genny's fire up. Then they run just like they have gasoline in them. I could switch to propane, or gasoline if I wished. I use my generators in series to give make a 4000 generator. I have wired a plug feed into my home panel's and I can feed the entire house when the juice goes down. I can't run A/C, but I can run everything else. Around here, it's hurricane backup I'm interested in.

If the natural gas goes down, I still have the opportunity to use real gasoline. In a real hurricane, the gas stations won't be working either.

You have to watch the gas pressure after a bad storm.. So many gen sets running that the line pressure drops too low.

At least that's the problem we have here in the heart of natural gas country when a hurricane hits.

I just siphon gas out of my boats after bad hurricanes. With ~250 gallons worth, it'd have to be a pretty bad storm before I ran out - worse than Katrina.

FWIW I have a tri power genny (gas, nat gas, propane) As stated , different fuels change the rating. Mine is 8k on gasoline but drops to 5500 on nat gas...(not sure on the propane number but pretty sure it closer to nat gas than gasoline). During Sandy , we got flooded and the utlility shut the nat gas. for the whole area. Then they came to each house to shut it off at your meter. Once they turned it back on they again had to come to each house, open the valve and re light everything. This whole process took several days . Of course the gas stations had no electricity to pump gas either but I had about 5 gals laying around and was able to run off that a little each day just to keep the freezer/ refrigerator cold. I like the flexibility of the tri fuel and the nat gas is so much easier than going out to get gasoline.(as long as its not a total disaster where they turn it off). Its also easy to stage your stuff on the lower rating if you have to(run one freezer for a few hours and then the refrigerator for a few hours rather than both at the same time.) We had no power for eleven days, but between my gas, when the utility turned the nat gas back on, and gasoline that I was able to get , we didnt lose our freezer which was full..and we had some heat because then it friggin snowed !
