The best way to drain the tank would be to disconnect the fuel line after the shutoff valve. You could disconnect the line either where it attaches to the carburetor or to the shutoff valve. My recommendation would be to disconnect at the shutoff, by the following steps:
1). Turn fuel valve to the “OFF” position.
2). Empty the fuel from the carburetor. To do this, with fuel valve “OFF”, start the engine. It should run for 20-90 sec, depending on how much fuel is in the carburetor bowl.
3). With your thumb, push firmly on the red shutoff valve until becomes dislodged from its holder. With the valve loose, the spring clamp is more accessible.
4). Identify which hose leads to the carburetor. Using a pliers, squeeze the spring clamp and move along the fuel line to clear the valve.
5). With a twisting motion, pull the carburetor fuel line off the shutoff valve. Beware that there may still be a few drops of fuel in the line. DO NOT disconnect the line connecting the fuel tank to the drain valve.
6). Now the tank can be drained. Depending on the size/shape of the container used to collect the fuel, it can be drained directly into this container or could attach a length of fuel line to the valve to facilitate the safe removal. It may also be helpful to open the tank cap.
7). With the tank empty, re-install the line to the carburetor back onto the fuel valve, placing the spring clip in the same position it was located at from the factory. Now the shutoff valve can be re-installed into its holder by again turning the valve to the “OFF” position, aligning the valve handle with the vertical slot in the valve holder, and push on the backside of the valve until it snaps in place. The unit should now be ready for storage.
