As winter's icy grip loosens and the snowplows are finally put away, your trusty snowblower deserves a well-earned rest. But before you tuck it away in the garage or shed, there's one crucial maintenance step that can prevent a host of future problems: draining the gasoline. Leaving fuel in the tank over the warmer months can lead to gumming, corrosion, and difficult starting when the snow flies again.
This article will guide you through the safe and effective process of draining the gas from your snowblower. We'll cover the necessary tools, the step-by-step procedure, and important safety precautions to ensure you protect both your equipment and yourself. By following these instructions, you'll be well-prepared for the next snowfall and extend the lifespan of your snowblower.
Why Draining Your Snowblower's Gas is Essential
Gasoline, especially when left to sit for extended periods, is not a stable substance. Over time, its volatile components evaporate, leaving behind a gummy residue. This residue can clog fuel lines, carburetors, and fuel filters, making it incredibly difficult to start your snowblower when you need it most. This is a common cause of a snowblower failing to start after sitting through the summer.
Furthermore, modern gasoline often contains ethanol, which can absorb moisture from the air. This water can lead to corrosion within the fuel system and the fuel tank itself. This internal damage can be costly to repair and can significantly shorten the operational life of your snowblower's engine. Regular draining prevents these damaging reactions from occurring.
By taking the proactive step of draining the fuel, you are essentially performing preventative maintenance. This simple task can save you from frustrating troubleshooting sessions, expensive repairs, and the inconvenience of a snowblower that won't work when you're facing a blizzard. It's a small effort for a significant return in reliability and longevity.
Gathering Your Tools and Supplies
Before you begin, ensure you have the necessary tools and supplies readily available. You will need a clean, approved gasoline container to store the drained fuel. This container should be specifically designed for gasoline storage and have a secure lid. A funnel is also essential for cleanly transferring the fuel from the snowblower's tank to the container.
You'll also want some absorbent rags or paper towels to clean up any minor spills. A small hand pump, often referred to as a siphon pump, is the most common and safest tool for draining the fuel. These are readily available at auto parts stores or hardware stores. Alternatively, if your snowblower has a drain plug at the bottom of the fuel tank, you might need a wrench of the appropriate size to remove it.
Finally, always work in a well-ventilated area, away from any open flames or sparks. Wear safety glasses to protect your eyes from any splashes and consider wearing fuel-resistant gloves to protect your skin. Having everything organized beforehand will make the draining process smoother and safer.
Step-by-Step: Draining Fuel with a Siphon Pump
The most common and recommended method for draining fuel is using a siphon pump. First, ensure your snowblower is on a level surface. Locate the fuel tank and the fuel line that connects it to the carburetor. You may need to consult your snowblower's owner's manual to identify these components.
Insert one end of the siphon pump's hose into the fuel tank, ensuring it reaches near the bottom. Place the other end of the hose into your approved gasoline container, making sure the container is positioned lower than the fuel tank. Begin pumping the handle of the siphon pump to create suction. Once fuel starts flowing, the pump will continue to siphon the gas until the tank is empty or the hose is lifted out of the fuel.
Continue siphoning until no more fuel is being drawn. It's a good idea to tilt the snowblower slightly towards the fuel tank opening to ensure as much fuel as possible is removed. Once done, carefully remove the hose from the tank and the container, and securely cap both.
Alternative Method: Using a Drain Plug
Some snowblower models are equipped with a drain plug located at the very bottom of the fuel tank. If yours has one, this can be a quicker method for draining. First, place your approved gasoline container directly beneath the drain plug.
Using the appropriate wrench, carefully loosen and remove the drain plug. Be prepared for the fuel to start flowing immediately. Allow the fuel to drain completely into the container. Once the tank is empty, clean the drain plug and the area around the opening with a rag.
Reinstall the drain plug, ensuring it is tightened securely but not overtightened, which could strip the threads. If you are unsure about the torque specification, consult your owner's manual. This method is efficient but requires careful handling to avoid spills.
Storing the Drained Fuel and Final Steps
The gasoline you've drained should be stored in a properly labeled, approved gasoline container. Never store gasoline in unapproved containers like milk jugs or glass bottles, as these can degrade and leak, posing a significant fire hazard. Store the container in a cool, dry, well-ventilated area, away from any heat sources, open flames, or sparks.
Once the fuel tank is empty, it's a good practice to run the engine for a minute or two until it stalls. This will help clear any residual fuel from the carburetor and fuel lines, further preventing gumming. After the engine has stalled, you can also wipe down the exterior of the fuel tank and the surrounding area with a clean rag to remove any fuel residue.
Consider adding a fuel stabilizer to the empty tank before storing it for the off-season. This is especially beneficial if you anticipate storing the snowblower for more than a few months. The stabilizer will help prevent any remaining moisture from causing corrosion and will keep any trace amounts of fuel from degrading.
Key Takeaways
- ✓ Draining fuel prevents gumming and corrosion in the fuel system.
- ✓ Use an approved gasoline container and a siphon pump or drain plug.
- ✓ Work in a well-ventilated area and wear safety gear.
- ✓ Running the engine until it stalls helps clear the carburetor.
- ✓ Fuel stabilizers can offer additional protection for long-term storage.
Frequently Asked Questions
How often should I drain the gas from my snowblower?
It is highly recommended to drain the gasoline from your snowblower at the end of the snow season, before storing it for the warmer months. This preventative maintenance ensures it will start reliably next winter.
Can I just leave a little bit of gas in the tank?
No, it's best to drain the tank as completely as possible. Even a small amount of fuel can degrade over time and cause issues. Running the engine until it stalls after draining is crucial to clear the carburetor.
What should I do with the drained gasoline?
Store the drained gasoline in a clean, approved gasoline container in a cool, dry, well-ventilated area away from heat sources or open flames. You can use this fuel in other small engines that require gasoline, or dispose of it responsibly at a local hazardous waste collection site if it's old or contaminated.
Is it safe to siphon gas by mouth?
Absolutely not. Siphoning gasoline by mouth is extremely dangerous and can lead to serious health risks due to the toxic fumes and the possibility of ingesting the fuel. Always use a mechanical siphon pump.
My snowblower has a fuel filter. Do I need to drain that too?
While draining the tank is the primary step, if your snowblower has a serviceable fuel filter, it's a good time to inspect it. If it appears clogged or damaged, consider replacing it during your off-season maintenance. However, the main concern for storage is the fuel in the tank and carburetor.
Conclusion
Draining the gasoline from your snowblower before storing it for the off-season is a simple yet vital maintenance task. By following the steps outlined in this guide, you can effectively remove fuel, prevent the formation of gum and varnish, and protect your engine's fuel system from corrosion. This proactive approach will save you time, money, and frustration when the first snowflakes begin to fall again.
Take the time to properly prepare your snowblower for its summer slumber. Gather your tools, work safely, and ensure the drained fuel is stored or disposed of responsibly. A well-maintained snowblower is a reliable snowblower, and this simple draining procedure is a cornerstone of that reliability.
