Given that generators are generally an expensive home product, you need to take excellent care of them in order to keep them from failing during use.This article presents a quick easy guide on how to drain the gas from your generator and your generator’s carburetor prior to storage. It’s important to do this if you will be storing the tank for over two months without anticipated use. If you do not do this, then it is necessary to use a gas stabilizer. Generators are generally an expensive home product so you need to take excellent care of it in order to keep it from failing during use.

Open the gas tank cap to create air flow through tank.
Locate the fuel valve switch. Turn it to the position in which it can be pushed back through the plastic cover over the fuel lines.
Remove the plastic cover that is over the fuel lines. This needs to be done in order to make it easier to access the fuel lines. This should be fairly easy to do; there are generally a couple of large bolts holding the cover in place.
You will need a wrench or socket wrenches to remove the cover.
Push the fuel valve through the cover. Move the cover out of the way.
Make sure that the fuel valve is set to off. This is so that the fuel valve is closed when you remove one side of the line in the next step.
Pinch and remove the aluminum clip off the side of the fuel line that does not connect to the gas tank. Have a rag close by to catch a little gas that is left in the tube you are removing (the tube that runs to the carburetor). Then remove the tube from the fuel valve. You may need to use pliers the first time because it’s sealed fairly tightly. Do not disconnect the line that runs to the gas tank, or gas will pour everywhere.
Put the fuel valve tube into a collection container large enough to hold all the gas in the tank. This will generally be about 5–10 gallons (18.9–37.9 L). You can use a gas can so that you can put the gas into your car so it doesn’t go to waste.
Turn the fuel valve to on. Let all of the gas drain out into the container until no more comes out. Once you’re done, reconnect the fuel line and replace the cover.
Locate the carburetor. There will be a screw on the base of the carburetor that is used to open the drain. Sometimes it is labeled on the generator. See your generator’s instruction manual to help you locate it.
Place a small collection container under the carburetor. Turn the screw to the left to open the drain hole. Only a small amount will come out.
Once the gas has stopped coming out, turn the screw to the right to close again.
