Yes, you can learn how to drain gas from a snowblower yourself. It’s a simple job that keeps your machine running well for years and prevents costly repairs.
Leaving old gas in the tank over the summer is a bad idea. It turns into a gummy mess that clogs up the small parts inside the engine. This is the main reason snowblowers won’t start when winter comes back around.
I’ve helped many friends fix this exact problem. The process is not hard, but you need to follow the right steps. Doing it wrong can make a big mess or even cause a safety issue.
This guide will walk you through the whole thing. I’ll show you the safe way to get the fuel out and get your machine ready for storage.
Why You Need to Drain the Gas
Gasoline does not last forever. It starts to break down after about 30 days. This is especially true for the fuel used in small engines.
The broken-down fuel leaves behind a sticky residue. This residue clogs the carburetor and the fuel lines. A clogged carburetor is the top reason for a snowblower that won’t start.
Learning how to drain gas from a snowblower stops this problem before it starts. It’s a form of preventive care for your engine. Think of it like changing the oil in your car.
It also prevents water from building up in the fuel system. Water can get in through condensation in a partly full tank. This water can cause rust inside the metal parts.
Draining the tank is the best practice for seasonal equipment. The Consumer Reports website recommends it for all lawn and garden tools. It extends the life of your machine by a lot.
It saves you money on repairs and expensive fuel system cleaner. It also saves you the frustration of a non-starting machine during a snowstorm. Trust me, you don’t want that headache.
Gather Your Tools and Supplies First
You don’t need fancy tools for this job. You probably have most of these items in your garage already. Getting them ready first makes the job go much smoother.
You will need a siphon pump or a hand pump. This is the main tool for how to drain gas from a snowblower tank. A simple, cheap pump from the auto parts store works great.
Get a fuel-safe container to catch the old gas. A metal gas can or a dedicated fuel container is best. Never use a milk jug or something not made for fuel.
Have some clean rags or paper towels ready. Spills will happen, and you want to wipe them up fast. You’ll also need a pair of safety glasses to protect your eyes.
A pair of work gloves is a good idea too. They keep gas off your skin and give you a better grip. Lay down a tarp or cardboard under the snowblower if you’re working in a nice area.
Finally, have a funnel and a fresh gas can ready. You might want to add new stabilizer-treated gas after you finish the drain. Or you might just leave the tank empty for storage.
Step-by-Step Guide to Draining the Fuel Tank
First, move your snowblower to a well-ventilated area. Do this work outside or in an open garage. Gas fumes are strong and can be dangerous in a closed space.
Turn the fuel valve to the “Off” position if your model has one. This valve is usually on the fuel line between the tank and the engine. It stops new gas from flowing into the line while you work.
Let the engine run until it uses up the gas in the carburetor. This step is key for learning how to drain gas from a snowblower completely. A dry carburetor is your goal for storage.
Place your empty gas can on the ground next to the machine. It needs to be lower than the snowblower’s fuel tank. Gravity helps the siphon work.
Insert the siphon pump tube into the snowblower’s gas tank. Put the other end into your empty gas can. Follow the pump’s instructions to start the flow.
Pump until no more fuel comes out. You might need to tilt the machine slightly to get the last bit. Be careful not to tip it over.
How to Drain the Carburetor Bowl
The fuel tank is not the only place gas hides. The carburetor has a small bowl at the bottom that holds fuel. You must empty this part too.
Locate the carburetor on your engine. It’s usually a small, metal box with a fuel line going into it. On the very bottom, you’ll find a small bolt or a drain plug.
Place your drain pan or a small cup directly underneath this bolt. The amount of gas here is small, but it’s important to catch it. This is a crucial part of how to drain gas from a snowblower fully.
Use the correct size wrench to loosen the drain bolt slowly. Do not remove it all the way at first. Let the fuel drip out into your container.
Once it stops dripping, you can remove the bolt completely. Check the bowl to make sure it’s empty. You might see some sediment or gunk come out with the gas.
Clean the bolt and the sealing area with a rag. Then screw the bolt back in and tighten it snugly. Don’t over-tighten it, or you could strip the threads.
Using a Fuel Stabilizer Instead
Some people prefer not to drain the tank completely. They use a product called fuel stabilizer. This is another valid method for off-season storage.
You add the stabilizer to a full tank of fresh gas. Then you run the engine for a few minutes. This pulls the treated gas through the entire fuel system.
The stabilizer keeps the gasoline from breaking down for many months. It prevents the formation of gum and varnish. The Environmental Protection Agency notes that proper fuel management reduces emissions from small engines.
This method is easier than learning how to drain gas from a snowblower. You don’t have to deal with siphoning or old fuel disposal. It’s a good option if you store the machine in a dry place.
However, I still recommend running the carburetor dry. Even with stabilizer, the gas in the carb bowl can evaporate and leave residue. The best practice is to use stabilizer AND run the carburetor dry.
If you choose this route, make sure you use the correct amount of stabilizer. Read the bottle’s instructions carefully. Too little won’t work, and too much is a waste of money.
How to Dispose of Old Gasoline Safely
You now have a container of old gas. You cannot just pour it down the drain or on the ground. That is illegal and very bad for the environment.
Check with your local waste management department. Many towns have hazardous waste collection days. They will take old gasoline and other chemicals for proper disposal.
Some auto parts stores or repair shops will also take it. Call around to see if this is an option in your area. Never mix it with used motor oil.
If the gas is relatively fresh and clean, you might be able to reuse it. You can mix a small amount into your car’s nearly full gas tank. The car’s large fuel system can handle a little old gas.
Do not put old gas back into your small engine. The whole point of learning how to drain gas from a snowblower is to get rid of the bad fuel. Putting it back in defeats the purpose.
Store the old gas container in a safe, cool place until disposal. Keep it away from heat sources and out of reach of children. Label it clearly so no one mistakes it for good fuel.
Common Mistakes to Avoid
The biggest mistake is not doing it at all. Letting gas sit for months is asking for trouble. Your future self will thank you for taking the time now.
Another error is using the wrong type of container. Use only containers approved for gasoline storage. Plastic fuel cans are cheap and easy to find.
Do not use a vacuum or mouth to start a siphon. This is extremely dangerous. Inhaling gasoline can cause serious lung damage.
Forgetting to drain the carburetor bowl is a common oversight. When you learn how to drain gas from a snowblower, remember the carburetor. That little bit of fuel is often the culprit.
Working near an open flame or spark is a major safety risk. This includes cigarettes, pilot lights, and electrical tools. Gasoline vapors are highly flammable.
Finally, don’t rush the job. Take your time and do it right. A calm, methodical approach is safer and more effective.
Tips for Easier Fuel System Maintenance
Use ethanol-free gasoline if you can find it. Ethanol attracts water and causes fuel to break down faster. Many small engine repair shops sell it.
Always add fuel stabilizer to your gas can when you fill it. This way, every bit of gas going into your snowblower is already treated. It becomes a habit, not an extra step.
Keep a log of when you perform maintenance. Write down the date you learned how to drain gas from your snowblower. Note it for next season.
Consider installing an in-line fuel shut-off valve if your model doesn’t have one. It makes running the carburetor dry much simpler. You just turn the valve and let the engine stall.
Store your snowblower in a dry, covered area. A damp environment promotes condensation inside the fuel tank. A dry shed or garage is ideal.
At the start of the season, always use fresh gas. Don’t use gas that’s been sitting in your can all summer. Start with a clean slate for the best performance.
What to Do After Draining the Gas
Your fuel system is now empty and safe for storage. But you’re not quite done yet. A little extra care will make spring start-up a breeze.
While you have the tools out, consider changing the engine oil. Old oil contains acids that can damage engine parts over the summer. The American Society of Mechanical Engineers highlights the importance of lubricant maintenance.
Check the spark plug. If it looks worn or corroded, replace it now. A new spark plug is cheap and guarantees a good spark next winter.
Inspect the scraper bar and paddles on the auger. Look for excessive wear or damage. Order any replacement parts now, not during the first snowstorm.
Apply a light coat of oil to the auger shaft and any other bare metal parts. This prevents rust during storage. You can use a simple spray lubricant.
Finally, cover the machine with a breathable cover. A plastic tarp can trap moisture and cause rust. A canvas or fabric cover is a better choice.
