Generators are often a backup plan. It’s always important to make sure your generator is in good shape because there’s nothing worse than thinking you have a solid plan B, just to find out your generator’s engine is dead.
Generators are also an expensive home product, so letting one fall into disrepair can amount to a hefty repair or replacement bill.
That being said, if you plan on storing your generator for two months or longer, it is imperative to drain the gas from your generator’s gas tank and carburetor.
Here are the steps for doing just that.
Draining the gas from your generator’s gas tank and carburetor
1. Twist off the gas tank cap to allow airflow in the tank.
2. Find the switch for the fuel valve. Turn the switch until you can push it through the plastic cover (or the maintenance cover) protecting the fuel lines.
3. Remove the maintenance cover. Loosen the large bolts securing the cover. Make sure the fuel valve is off and push the valve through the cover.
4. Take off the clip on the side of the fuel line that isn’t connected to the gas tank. Pinching the aluminum clip for removal should suffice. Have a rag at the ready to catch the little gas remaining in the tube that runs to the carburetor. Remove the tube from the fuel valve. Make sure not to remove or dislodge the tube that runs to the gas tank. Making that mistake will cause gas to drain everywhere (which would be a very unpleasant time to clean up).
5. Place the fuel valve into a container large enough to hold 5-10 gallons of gas.
6. Switch the fuel valve to on. Allow the gasoline to drain into the container until the fuel tank is empty. Once it is drained, reattach the fuel valve and screw the cover back into place.
7. Find the carburetor. There is usually a screw at the base of the carburetor that is responsible for opening the carburetor bowl or “float bowl.” If you can’t find it, reference the page in your owner’s manual or shop manual that covers the carburetor.
8. Position a container under the carburetor. Turn the screw to open the drain and allow the gas to flow into the container (there should only be a small amount). Once the carburetor is empty, retighten the screw.
