The crisp air and falling snowflakes signal the arrival of winter, a season that can bring both beauty and the daunting task of snow removal. For homeowners equipped with a snowblower, this powerful machine is a winter essential. However, before stowing it away for the season or performing routine maintenance, understanding how to safely and effectively empty its gas tank is a crucial skill. Neglecting this step can lead to fuel degradation, engine issues, and potential safety hazards.
This article will guide you through the process of emptying your snowblower's gas tank, covering everything from necessary preparation and safety precautions to the actual draining methods and proper disposal of old fuel. By mastering this essential maintenance task, you'll ensure your snowblower remains in optimal condition for years to come, ready to tackle even the heaviest snowfalls with confidence.
Why Emptying Your Snowblower's Gas Tank is Essential
Regularly emptying the gas tank of your snowblower is a vital part of its upkeep, particularly when preparing for extended storage or before undertaking significant maintenance. Gasoline, especially ethanol-blended fuels, can degrade over time. This degradation can lead to the formation of varnish and gum deposits within the fuel system, clogging fuel lines, carburetors, and filters. These blockages can prevent the engine from starting or running smoothly when you next need it.
Furthermore, stale gasoline can absorb moisture from the air, leading to water contamination in the fuel. Water in the fuel system can cause corrosion and further damage to engine components. By removing the fuel, you eliminate the risk of these issues, ensuring a clean and functional fuel system for the next operating season. This proactive measure saves you time, money, and frustration when winter returns.
Beyond preventing fuel-related problems, emptying the tank is often a prerequisite for other maintenance tasks. For instance, if you need to service the carburetor, replace spark plugs, or perform any work that might involve tipping the snowblower, having an empty tank significantly reduces the risk of fuel spills and potential fire hazards. It creates a safer working environment and simplifies the overall maintenance process.
Safety First: Precautions Before You Begin
Before you even think about touching a wrench or a siphon hose, safety must be your absolute top priority. Gasoline is highly flammable, and its fumes are explosive. Always work in a well-ventilated area, preferably outdoors, away from any open flames, sparks, or heat sources. This includes pilot lights on water heaters, furnaces, or even static electricity generated by clothing. Ensure there are no smoking materials or ignition sources anywhere near your workspace.
Wear appropriate personal protective equipment (PPE). This includes chemical-resistant gloves to protect your skin from gasoline and its fumes, and safety glasses or goggles to prevent any accidental splashes from reaching your eyes. If you have long hair, tie it back securely. Avoid wearing synthetic clothing that can easily generate static electricity. Cotton or flame-resistant materials are a safer choice.
Ensure your snowblower is completely cool before you begin. A hot engine can ignite fuel vapors. Allow the machine to sit for at least 30 minutes after its last use to cool down. Also, make sure the snowblower is on a stable, level surface. This prevents it from tipping over during the process, which could lead to uncontrolled fuel spills and increased risk.
Method 1: Using a Siphon Pump
One of the most common and straightforward methods for emptying a snowblower gas tank is by using a siphon pump. These pumps are readily available at auto parts stores and home improvement centers. They typically consist of a flexible hose and a hand-operated bulb or a manual pump mechanism. The principle is simple: create a vacuum to draw the fuel from the tank into a separate container.
To begin, place an approved gasoline storage container on the ground, ensuring it is lower than the snowblower's fuel tank. Insert one end of the siphon hose into the snowblower's gas tank, pushing it down as far as it will comfortably go, ideally reaching the bottom to extract as much fuel as possible. Place the other end of the hose into the approved container. Then, operate the siphon pump according to its instructions. For bulb-style pumps, squeeze the bulb repeatedly until fuel begins to flow. For manual pumps, operate the handle to create suction.
Once the siphon is established and fuel is flowing into the container, you can often leave it to drain on its own. Keep an eye on the process to ensure the hose doesn't dislodge and to stop when the tank is nearly empty. Be careful not to overfill your storage container. After draining, carefully remove the hose, ensuring no residual fuel drips onto the ground.
Method 2: Draining Through the Carburetor Bowl
Another effective method, particularly for smaller amounts of fuel or when a siphon pump isn't available, involves draining the fuel directly from the carburetor bowl. The carburetor is the component that mixes fuel and air for combustion, and it has a small bowl at its base that holds a reserve of fuel.
Locate the carburetor on your snowblower's engine. You'll typically find a small drain screw or plug at the very bottom of the carburetor bowl. Place an approved gasoline container directly beneath this drain screw. Using an appropriate screwdriver or wrench, carefully loosen and remove the drain screw. Be prepared for fuel to immediately start flowing out into the container.
Allow the fuel to drain completely from the bowl. Once the flow stops, carefully reinsert and tighten the drain screw. This method is efficient for emptying the last vestiges of fuel from the system, but it may not remove all the fuel from the tank itself. It's often used in conjunction with a siphon pump or as a final step to ensure minimal fuel remains in the carburetor.
Proper Fuel Disposal and Storage
Disposing of old or drained gasoline requires careful consideration to protect the environment and comply with local regulations. Never pour gasoline down a drain, into the soil, or into regular trash. Most communities have designated hazardous waste disposal sites or collection events where you can safely and legally dispose of old fuel. Check with your local municipality or waste management authority for specific instructions.
If you plan to store the drained gasoline for later use (e.g., for a generator or other equipment), it must be stored in an approved, sealed gasoline container. These containers are designed to prevent evaporation and minimize the risk of spills or fumes escaping. Store these containers in a cool, dry, well-ventilated area, away from any ignition sources and out of reach of children and pets. It's generally recommended to use gasoline within a few months of purchase, as its quality degrades over time.
For long-term storage of the snowblower itself, after emptying the tank, it's a good practice to add a fuel stabilizer to the remaining fuel in the tank (if you didn't fully drain it) and run the engine for a few minutes. This circulates the stabilized fuel throughout the carburetor and fuel lines, protecting them from corrosion and deposits during the off-season. If you fully drained the tank, you can also run the engine briefly until it sputters and dies to ensure all fuel is cleared from the carburetor.

Frequently Asked Questions
How often should I empty my snowblower's gas tank?
It's most crucial to empty the gas tank when you are preparing to store your snowblower for an extended period, such as at the end of the winter season. If you only use your snowblower a few times a year, consider emptying it after each season of use to ensure fresh fuel when you need it.
Can I just run the snowblower until it runs out of gas?
While running the snowblower until it empties the tank can help clear some fuel from the carburetor, it's not a foolproof method for completely emptying the tank or preventing fuel degradation issues. Some fuel will always remain in the tank and lines, and running the engine dry can sometimes be hard on the fuel pump. Manual draining or siphoning is more thorough.
What kind of container should I use to collect the old gasoline?
Always use an approved gasoline storage container. These are typically made of durable plastic or metal and are specifically designed to safely store flammable liquids. They have tight-fitting lids to prevent evaporation and spills. Never use glass jars or unapproved plastic containers.
What if I accidentally spill some gasoline during the process?
If you spill a small amount of gasoline, absorb it immediately with absorbent pads or rags. Ensure the area is well-ventilated to allow the fumes to dissipate. Dispose of the soaked rags as hazardous waste. For larger spills, evacuate the area, eliminate all ignition sources, and contact your local fire department or hazardous materials team for guidance.
Can I reuse the gasoline I drained from my snowblower?
You can reuse drained gasoline if it is relatively fresh and has been stored properly in an approved container. However, if the gasoline is old, has been sitting for more than a few months, or shows signs of contamination (like cloudiness or a varnish-like smell), it's best to dispose of it responsibly rather than risk damaging your snowblower's engine.
Conclusion
