Leaving gasoline in the tank for extended periods can lead to a host of problems, from gummed-up carburetors to potential safety hazards.
This guide will walk you through the essential process of emptying your snowblower's fuel tank, ensuring its longevity and your safety. We'll cover why this maintenance is vital, the different methods you can employ, and the precautions you must take to avoid spills, fires, and damage to your equipment. By the end of this article, you'll have the knowledge and confidence to perform this task effectively.
Why Draining Your Snowblower's Fuel is Essential
The primary reason for draining your snowblower's fuel tank before storage is to prevent fuel degradation. Gasoline is a volatile substance that, over time, especially when exposed to air and temperature fluctuations, can break down. This breakdown process leads to the formation of varnish and gum deposits. These sticky residues can clog the fuel lines, the carburetor jets, and other critical components of the fuel system.
When these parts become clogged, your snowblower may refuse to start when the next snow season arrives, or it might run poorly, sputtering and losing power. Cleaning a gummed-up carburetor is a tedious and often expensive repair. By simply draining the fuel, you eliminate the root cause of this common and frustrating problem, saving yourself time, money, and a potential headache when you need your snowblower the most.
Furthermore, storing a snowblower with a full or partially full fuel tank can pose safety risks. Gasoline is highly flammable, and vapors can escape from the tank and carburetor, creating a fire hazard, especially in enclosed spaces like garages. While modern snowblowers have improved fuel containment, it's always best to err on the side of caution. Draining the fuel significantly reduces this risk, making off-season storage safer for your home and family.
Preparing for the Fuel Draining Process
Before you begin draining the fuel, it's crucial to gather the necessary tools and prepare your workspace. You will need a clean, approved gasoline storage container, preferably one designed for safe transport and storage of fuel. A funnel with a wide mouth will be essential for directing the fuel into the container without spills. You might also need a clean rag or shop towels to wipe up any minor drips.
Ensure you are working in a well-ventilated area, preferably outdoors, away from any open flames, sparks, or heat sources. This is paramount for safety, as gasoline fumes are highly flammable. It's also advisable to wear protective gloves and eye protection to prevent skin or eye contact with gasoline. Never smoke while handling fuel.
Finally, make sure your snowblower's engine is cool. Attempting to drain fuel from a hot engine can increase the risk of ignition due to hot components and fuel vapors. Allow the machine to sit for at least 30 minutes after its last use to cool down sufficiently.
Method 1: Siphoning the Fuel
One of the most common and straightforward methods for draining fuel is siphoning. This involves using a siphon pump or a length of flexible tubing to draw the gasoline from the tank into your storage container. Start by placing your approved fuel container on the ground, lower than the snowblower's fuel tank. Insert one end of your siphon tube into the fuel tank, ensuring it reaches the bottom.
Next, initiate the siphon. If you have a manual siphon pump, follow its instructions. If you're using a simple tube, you can either use a siphon starter bulb or carefully place the free end of the tube in your mouth and gently suck until fuel begins to flow, then quickly remove your mouth and direct the fuel into the container. Be extremely careful not to ingest any gasoline. Once the fuel starts flowing into the container, gravity will do the work.
Continue siphoning until the fuel tank is as empty as possible. You may need to tilt the snowblower slightly to get the last remnants of fuel out. Once done, carefully remove the siphon tube, ensuring no fuel spills. Seal your fuel container tightly and dispose of any residual fuel in the tube properly.
Method 2: Using the Carburetor Drain Screw
Many snowblowers are equipped with a drain screw on the carburetor bowl. This method can be more precise for emptying the fuel system. Locate the carburetor, which is typically a metal component connected to the engine where the fuel line enters. You'll find a small screw or bolt at the bottom of the carburetor bowl.
Place your fuel container and funnel directly beneath the carburetor drain screw. Carefully loosen the drain screw using an appropriate wrench or screwdriver. As you loosen it, fuel will begin to drain from the bowl into your container. Allow the fuel to drain completely.
Once the fuel has drained, carefully retighten the drain screw. Be sure not to overtighten it, as this can damage the threads. This method is effective for emptying the fuel that has made its way into the carburetor, which is often the most problematic fuel to leave sitting.
Alternative Methods and Safety Precautions
In some cases, if your snowblower's fuel tank has a built-in drain valve, you can simply open this valve to allow the fuel to flow into your container. Consult your snowblower's owner's manual to determine if your model has this feature and how to operate it. Regardless of the method used, always prioritize safety.
Never attempt to drain fuel indoors or near ignition sources. Ensure your fuel container is properly labeled and stored in a safe location away from children and pets. If you spill any fuel, clean it up immediately with absorbent rags and dispose of them properly. Gasoline is a hazardous material, and responsible handling is paramount.
Consider using a fuel stabilizer if you plan to store your snowblower with a small amount of fuel remaining in the tank, though complete draining is always the preferred method for long-term storage. A fuel stabilizer prevents fuel degradation and keeps the fuel system clean. However, for maximum protection and to avoid potential issues, emptying the tank entirely is the most reliable approach.

Frequently Asked Questions
How much fuel should I leave in the tank if I can't drain it completely?
If complete draining is not feasible, it is best to fill the tank to its capacity. A full tank minimizes the amount of air inside, which reduces condensation and the potential for rust formation within the tank. Additionally, adding a fuel stabilizer to this full tank will help prevent fuel degradation during storage.
What kind of container should I use to store the drained fuel?
You should use a clean, approved gasoline storage container that is specifically designed for this purpose. These containers are made of materials that are resistant to gasoline and have secure, tight-fitting caps to prevent vapor escape and spillage.
