- Prime the siphon: Suck on the siphon’s end to create a vacuum and draw fuel into the tubing. Alternatively, you can use a pump to start the siphon.
- Direct the gas: Guide the siphon’s outflow tube into the container you prepared for collecting the gas.
- Transfer the gas: The siphon will draw the gas from the tank and into the container.
- Monitor the tank: Keep a close eye on the gas tank’s level and stop the siphon when you’ve removed the desired amount of fuel.
- Securely store the gas: Properly seal the container and store it in a cool, dry, and well-ventilated area.
2. Draining the Tank Through the Fuel Line
What You Need:
- A container to collect the gas (such as a gas can)
- A wrench or pliers (to remove the fuel line)
Instructions:
- Locate the fuel line: The fuel line connects to the carburetor or fuel pump. It is usually made of rubber or plastic and may have a clamp securing it.
- Disconnect the fuel line: Carefully loosen the clamp or connection to disconnect the fuel line.
- Direct the fuel: Hold the fuel line over the container and allow the gas to drain out of the tank.
- Reconnect the fuel line: Once the tank is empty, reconnect the fuel line and secure it with the clamp.
3. Running the Engine Until Empty
Instructions:
- Start the engine: Turn on your lawn mower and let it run until the engine sputters and stops due to lack of fuel.
- Safety precautions: Never leave a running lawn mower unattended. Ensure proper ventilation and stay clear of the engine while it’s running.
