Is your Craftsman snowblower sitting idle after a long winter, or are you preparing for seasonal storage? One of the most crucial, yet often overlooked, maintenance steps is properly draining the fuel tank. This simple procedure can prevent a host of problems, from gummed-up carburetors to difficult startups next season.
This article will walk you through the essential process of draining your Craftsman snowblower's gas tank, ensuring its longevity and reliable performance. You'll learn why this maintenance is vital, discover the most effective methods, and gain the confidence to tackle this task yourself, saving you time and potential repair costs.
Why Draining Your Snowblower's Gas Tank is Essential
Gasoline, especially when left sitting for extended periods, is prone to degradation. Over time, it can absorb moisture from the air, leading to water contamination. This water can cause corrosion within the fuel system and, more significantly, lead to the formation of gummy deposits. These deposits can clog fuel lines, filters, and the carburetor's delicate jets, making it incredibly difficult to start the snowblower when you need it most.
Furthermore, modern gasoline formulations often contain ethanol, which is hygroscopic (attracts water) and can separate from the other fuel components over time, a process known as phase separation. This separated ethanol-water mixture is highly corrosive and can damage rubber and plastic components within the fuel system, leading to leaks and further complications. Draining the tank eliminates this risk entirely.
Regularly draining the fuel tank, particularly before storing the snowblower for the off-season, is a proactive maintenance step that pays significant dividends. It ensures that when you're ready to clear snow again, your Craftsman snowblower will fire up with minimal fuss, rather than requiring extensive troubleshooting and repairs.
Gathering Your Tools and Safety Precautions
Before you begin, it's important to gather the necessary tools and prioritize safety. You will need a clean, approved gasoline container with a capacity large enough to hold all the fuel from your snowblower's tank. A funnel with a wide mouth will be invaluable for transferring the fuel cleanly. You might also need a siphon pump, either manual or battery-operated, depending on the method you choose. A set of screwdrivers or wrenches might be necessary if you need to access the fuel line directly.
Safety is paramount when dealing with gasoline. Always work in a well-ventilated area, preferably outdoors, away from any open flames, sparks, or heat sources. Gasoline fumes are highly flammable. Wear safety glasses to protect your eyes from splashes and nitrile gloves to protect your skin from prolonged contact with fuel. Ensure your snowblower is turned off and has cooled down completely before you start. Never smoke while handling gasoline.
Having all your supplies ready and understanding the safety protocols will make the draining process smoother and significantly reduce the risk of accidents. A clean workspace also helps prevent debris from entering the fuel container or the snowblower's fuel system.
Method 1: Siphoning the Fuel
The most common and generally safest method for draining a Craftsman snowblower's gas tank is by siphoning. This involves using a siphon pump to draw the fuel out of the tank and into a designated container. If your snowblower has an easily accessible fuel cap and a relatively short distance to the tank's bottom, you might be able to use a simple manual siphon hose. For more convenience and efficiency, a battery-operated fuel transfer pump is an excellent investment.
To siphon, insert one end of the siphon hose or pump tube into the snowblower's fuel tank, ensuring it reaches as close to the bottom as possible to extract all the fuel. Place the other end of the hose or pump outlet into your approved gasoline container. If using a manual siphon, you'll need to create suction by either shaking the hose vigorously or using a priming bulb if your pump has one. Battery-operated pumps will typically have a simple on/off switch.
Once the fuel begins to flow, monitor the process closely. Avoid overfilling your collection container. Continue siphoning until no more fuel can be drawn from the tank. It's a good practice to run the engine for a minute or two after siphoning to burn off any residual fuel in the carburetor and fuel lines, ensuring they are as dry as possible.
Method 2: Draining via the Fuel Line
An alternative method, which can be more direct but requires a bit more mechanical familiarity, is to drain the fuel by disconnecting the fuel line. This method is particularly useful if siphoning proves difficult due to the tank's design or if you want to ensure the carburetor is completely empty of fuel.
Locate the fuel line that runs from the fuel tank to the carburetor. You may need to remove a shroud or cover to access it. Place your collection container directly beneath the fuel line connection point. Carefully use a wrench or pliers to loosen the clamp securing the fuel line to the carburetor or fuel filter. Once loosened, gently pull the fuel line off the fitting. Fuel will immediately begin to flow into your container.
Be prepared for the fuel to flow relatively quickly. Once the fuel has drained from the line and the tank, you can reattach the fuel line and secure the clamp. It's crucial to ensure the connection is tight to prevent leaks. After reattaching, you can then proceed to run the engine briefly to clear any remaining fuel from the carburetor, as mentioned in the siphoning method.
Post-Draining Procedures and Storage Tips
After successfully draining the fuel tank, it's advisable to add a small amount of fuel stabilizer to the empty tank. This helps protect the internal metal components from rust and corrosion during storage. You can also add a small amount of fresh gasoline (about a quart) to the tank and run the engine for a few minutes. This ensures that the fuel stabilizer circulates through the fuel system, coating the internal parts and preventing moisture buildup.
Clean the exterior of your Craftsman snowblower. Remove any accumulated dirt, grass, or salt. Inspect the auger, impeller, and shear bolts for any signs of wear or damage. Store the snowblower in a dry, protected location, such as a garage or shed. If possible, elevate the snowblower slightly off the concrete floor to prevent moisture absorption. Covering the snowblower with a breathable tarp can offer additional protection from dust and debris.
Proper storage goes beyond just draining the fuel. By taking these extra steps, you're not only protecting your investment but also setting yourself up for a hassle-free start to the next snow season.
