This past weekend, we had up to 10 hours running time in my RV with our Honda 2000 on 'ECO' mode. It was running the lights, furnace fan, fridge, radio, and about 300 watts of other equipment (we run telescopes, cameras, and laptops).

We were boondocking where generator sounds were not an issue since we had no neighbors.

Rather than have to 'gas up' first thing in the morning or top off, I am considering an extender gas can. So of course I have questions.

Given the photos of extender can products, is it true that the Honda siphons from the extender can? Is there a special cap for the Honda? Since I can run close to 10 hours on the gallon of fuel in the Honda, are there 2-3 gallon extenders? Are there preferred brands? Can I refuel the extender can while the Honda runs?


There is something special about camping in an RV.

Check out Utube videos on the subject. Some do refill the "remote" tank while running. Logic is not spilling gas on a hot engine. It seems like the generator does suction the gas and a few make their own extended range gas cap out of spare generator gas caps.

The Honda EU2000i has a small fuel pump and can suck the fuel out of an external tank. In order to do so you will need to modify your existing fuel cap or buy one already modified.

The basic premise is you remove the vent from the center of the cap and replace it with a barbed fitting. Then put a fuel safe hose on the barbed fitting and run it over to your extended run tank.

As far as refueling while the generator is on, well that's up to you with how you hook to the extended tank and possibly how far away the tank is from the generator.

there are replacement caps available on Amazon. But the reviews aren't all that good. I like this youtube video as it shows how to use your existing cap and also includes all the parts in the description.

The extender kits usually use a standard outboard motor fuel tank. If you are concerned that the fuel line is too close to the running generator, simply disconnect and move away to fill it. If you do it quickly there will not be enough vacuum to shut it down. An alternative is to have two tanks and swap them out, they have quick disconnects.

One thing to watch is the surface of the generator gas tank opening. Those stupid government gas cans that have the push to fill can nick the surface and allow an air leak that prevents the draw from the remote tank.

It does have a fuel pump.. I purchased a set up from here - Amazon - Bergs Single system

BUT I purchased the dual feed system and still have that tucked away in my shed ..

Mine was a 5 gallon and was/IS awesome ! I also fueled mine up while the generator was running as the tank was a few feet from the generator..

I know a few folks who tried some of the amazon/ebay no name systems and they were not trouble free or easy to use. I have the dual unit Berg system and while more expensive IMHO it is worth the money. Very well designed, quick and easy to connect, and very good fuel cap for the honda.

Go to ebay or amazon and buy an extended run gas cap, then you can either buy locally or through ebay/amazon a boat gas tank that you like. Then all you need is the fittings to go from the new gas cap to the hose, then to the tank. If you have an outboard boat, use that model.

It is that simple, no need to pay someone a lot of extra money to get those things for you unless you prefer to.

I have a six and a half gallon tank with dual outlets so I can run both generators on one tank if I want to use air conditioning, and a three gallon that is much easier to deal with for one generator.
