Draining Gas from Toro Snowblower: The Ultimate Guide to Prevent Costly Repairs
As winter fades and spring approaches, a crucial task for every Toro snowblower owner emerges. Failing to properly prepare your machine for off-season storage is the single biggest mistake that leads to frustrating, expensive problems next winter. The primary culprit? Old gasoline left sitting in the tank and carburetor.
Untreated gasoline begins to degrade in as little as 30 days. Modern ethanol-blended fuels accelerate this process, absorbing moisture from the air and forming gummy deposits and varnish. This sludge clogs the tiny passages in the carburetor, leading to a snowblower that refuses to start when you need it most.
This guide provides a definitive, step-by-step process for draining fuel from your Toro snowblower. Following these instructions will save you from the headache of a non-starting machine and the significant cost of a professional carburetor cleaning or rebuild.

First Things First: Critical Safety Precautions
Gasoline is highly flammable and its vapors are explosive. Prioritize safety above all else when performing this maintenance. Adhering to these precautions is not optional; it’s essential for protecting yourself and your property.
Always work in a well-ventilated area, preferably outdoors or in a garage with the doors wide open, to prevent the buildup of fumes. Ensure the snowblower’s engine is completely cool to the touch before you begin. A hot engine or exhaust can easily ignite gasoline. Lastly, keep all sources of ignition far away from your work area—this includes cigarettes, pilot lights on water heaters or furnaces, and any power tools that could create a spark.
Essential Gear for the Job
Before you start, gather the necessary protective gear and tools. You will need safety glasses to protect your eyes from accidental splashes and chemical-resistant gloves to protect your skin from gasoline. You’ll also require an approved gasoline container for storing the old fuel, a siphon pump or basic hand tools like pliers and a socket set, and some rags or shop towels for inevitable drips and spills.
Choosing Your Method: How to Drain the Fuel
There are three primary methods for removing fuel from your Toro snowblower. The best method for you depends on your comfort level with small engine maintenance and the tools you have available. Each technique effectively removes the bulk of the fuel, which is the most important goal.
The siphon pump method is the cleanest and requires no tools, while disconnecting the fuel line is more thorough. The “running it dry” method is simplest but has some drawbacks. Understanding the pros and cons of each will help you make an informed decision.
| Method | Difficulty | Tools Required | Pros | Cons |
|---|---|---|---|---|
| Siphon Pump | Easy | Manual Siphon Pump | Clean, fast, no disassembly needed. | May not remove every last drop of fuel. |
| Disconnect Fuel Line | Moderate | Pliers, Catch Pan | Very thorough, drains tank and line. | Can be messy if not careful. |
| Run Engine Dry | Easy | None | Simple, uses up remaining fuel. | Leaves fuel in carburetor bowl. |
Method 1: Using a Siphon Pump (The Cleanest Approach)
Using a manual siphon pump is often the easiest and most popular way to drain a snowblower’s gas tank. These inexpensive pumps are readily available at auto parts and home improvement stores.
Start by placing your approved gasoline container on the ground, ensuring it is lower than the snowblower’s gas tank. Remove the gas cap from the snowblower and insert the siphon’s intake hose into the tank, pushing it to the lowest point. Place the outlet hose securely into the gas container. Begin pumping the siphon bulb to create suction. Once the fuel starts flowing, gravity will take over and continue the process until the tank is empty.

Method 2: Disconnecting the Fuel Line (The Most Thorough Approach)
For those who want to be as thorough as possible, disconnecting the fuel line is the best option. This method drains the tank, the fuel filter, and the line leading to the carburetor. You will need to locate the fuel line, which is typically a black rubber hose running from the bottom of the gas tank to the side of the carburetor.
Place a suitable drain pan or container under the carburetor connection point. Using a pair of pliers, squeeze the tabs on the small metal spring clamp holding the fuel line to the carburetor and slide it up the hose. Gently twist and pull the fuel line off the carburetor inlet. Fuel will immediately begin to flow, so be prepared. Allow the tank to drain completely before reattaching the hose and securing the clamp.
Method 3: Running the Engine Dry (The “Use It or Lose It” Approach)
If you only have a small amount of fuel left at the end of the season, the simplest option may be to just run the snowblower until it stops. Do this in a safe, open area away from your home. While this method is easy, it is not the most complete.
The engine will stall once the fuel level in the tank is too low for the pickup to draw from. However, a significant amount of gasoline will still remain in the carburetor float bowl. If you choose this method, it is absolutely essential that you perform the additional step of draining the carburetor bowl afterward.
The Most Important Step: Draining the Carburetor Bowl
This is the step that most people miss, and it’s the one that causes the most problems. Even after the tank is empty, the carburetor’s float bowl still holds a small reservoir of fuel. Leaving this fuel over the summer is a guaranteed way to clog the main jet and cause starting issues.
Locate the carburetor on your Toro engine. At the very bottom, you will find a small bowl, typically held in place by a bolt in the center. Look for a smaller drain screw or bolt on the side of this bowl, often requiring a 10mm wrench or a flathead screwdriver. Place a small cup or rag underneath, loosen this screw a few turns, and the remaining fuel will drain out. Once it stops dripping, tighten the screw snugly. This single action is the most effective preventative maintenance you can perform.
Handling and Disposing of Old Gasoline
Now that you’ve drained the fuel, you must handle it responsibly. Never pour old gasoline down a drain or onto the ground. It is a hazardous material that can contaminate soil and groundwater.
If the fuel is less than a couple of months old and was treated with a stabilizer, it can often be used by diluting it in a nearly full tank of gasoline in your car. A small amount of old, stabilized fuel will not harm a vehicle’s engine. If the fuel is very old, smells like varnish, or contains visible debris, it should be taken to a local hazardous waste disposal facility. Check your city or county’s website for information on collection sites and events.
Common Mistakes and How to Avoid Them
Even a straightforward task like draining fuel can have pitfalls. One common issue is a siphon pump that won’t start the flow. This is usually because the outlet container is not positioned significantly lower than the gas tank, preventing gravity from assisting the flow. Ensure there is a good height difference.
Another mistake is overtightening the carburetor drain screw. This small screw can be easily stripped. It only needs to be snug enough to prevent a leak, not torqued down with excessive force. Finally, forgetting to put the gas cap back on before storing the machine can allow moisture and debris to enter the tank over the summer, creating new problems. Double-check that the cap is secure as your final step.
Beyond the Fuel: Preparing for Next Season’s Success
With the fuel system properly drained, your Toro is well on its way to a trouble-free start next winter. This is also the perfect time to perform other end-of-season maintenance. Clean any road salt and grime off the housing and auger to prevent rust, check the oil level, inspect the scraper blade and paddles for wear, and check the spark plug.
Proper storage is just as vital as proper maintenance. The reliability of your machine is paramount when the snow starts to fall, a factor many consider when looking into a Toro vs Craftsman snow blower comparison. Storing your snowblower in a clean, dry location like a garage or shed will protect it from the elements and ensure it remains in top condition.
Conclusion: A Simple Task That Prevents Major Headaches
Draining the gas from your Toro snowblower is a simple, 15-minute task that can save you hundreds of dollars in repairs and countless hours of frustration. By making it a non-negotiable part of your end-of-season routine, you ensure your machine is protected from the damaging effects of old fuel.
When the first blizzard of the season arrives, you can have confidence that your well-maintained Toro will start on the first or second pull. This small investment of time is the key to reliable performance, season after season.
