Yes, you can do it yourself – learning how to drain snow blower gas tank is a key skill for spring storage. It stops old gas from gunking up your carburetor and causing big problems next winter.
I see it every year. People put their snow blower away with gas still in it. Come next snowfall, the engine won’t start. It’s a real headache you can avoid.
I’ve worked on dozens of small engines over the years. Draining the fuel is the single best thing you can do for your machine. It takes less than 30 minutes and saves you a lot of money.
This guide will show you the simple steps. You’ll learn how to drain snow blower gas tank safely and correctly. We’ll cover all the tools you need and common mistakes to skip.
Why You Need to Drain the Gas Tank
Gas doesn’t last forever. It breaks down over time, especially when it sits for months. This is the main reason you need to learn how to drain snow blower gas tank.
Old gas turns into a sticky varnish. This gunk clogs the tiny passages in your carburetor. A clogged carburetor means your engine won’t get the fuel it needs to run.
The US Forest Service notes that proper small engine care prevents fires. Stale fuel left in equipment is a risk. Draining it is a safe practice.
Think of it like this. You wouldn’t leave milk in a cup all summer. You’d clean it out. Your snow blower’s fuel system needs the same care.
Doing this one task saves you from a costly repair bill. A carburetor clean or rebuild can cost over a hundred dollars. Draining the tank costs you nothing but a little time.
It also makes next winter much easier. Your machine will start on the first or second pull. You won’t be fighting with it while snow piles up on your driveway.
When to Drain Your Snow Blower Gas
Timing is everything. You need to know the right moment to drain the fuel. The best time is at the end of the snow season, before you store the machine.
Don’t wait until fall. Gas left in the tank over spring and summer will go bad. It will cause the problems we just talked about.
I do mine right after the last big snow melt. The weather is warming up, and I know I won’t need the blower for months. This is the perfect window.
If you’re putting the snow blower away for more than 30 days, drain the tank. That’s a good rule of thumb. Short breaks are okay, but long storage needs an empty tank.
Some people use fuel stabilizer instead. This is a chemical you add to fresh gas. It slows down the breakdown process for a few months.
But here’s my take. Learning how to drain snow blower gas tank is more reliable. You don’t have to buy a product or guess if it worked. An empty tank is a sure thing.
Tools and Supplies You Will Need
You don’t need fancy tools. Most items are probably already in your garage. Let’s go over the simple list for how to drain snow blower gas tank.
First, get a fuel container. This is for the old gas. Use a proper gas can, not a milk jug or water bottle. Safety is key here.
You’ll need a length of clear vinyl tubing. About three feet is good. The tube should fit snugly over the fuel line or into the tank’s opening.
Have some rags or paper towels ready. Spills happen, even when you’re careful. Wiping up gas right away is important.
Wear safety glasses. Fuel can splash, and you don’t want it in your eyes. A pair of gloves is also a smart idea to protect your skin.
You might need a pair of pliers or a screwdriver. This depends on your snow blower model. Some have a clamp on the fuel line you need to loosen.
That’s really it. A simple setup for a simple job. Now let’s get into the actual steps for how to drain snow blower gas tank.
Step-by-Step Guide to Draining the Tank
Let’s walk through the process. Follow these steps in order for the best results. This is the core of how to drain snow blower gas tank.
First, move your snow blower to a well-ventilated area. Do this outside if you can. You don’t want to breathe in gas fumes in a closed space.
Turn the fuel valve to the “off” position. This valve is usually on the fuel line between the tank and the carburetor. It stops new gas from flowing.
Place your empty gas can on the ground next to the machine. It needs to be lower than the snow blower’s fuel tank. Gravity will help the fuel flow down.
Find the fuel line that goes from the tank to the carburetor. It’s a small rubber hose. Carefully disconnect it at the carburetor end.
Slide your clear tubing onto the end of the fuel line. Put the other end of the tube into your gas can. Make sure it’s secure so it doesn’t pop off.
Now, turn the fuel valve back to the “on” position. The gas should start flowing through the tube and into your can. Let it drain until the tank is empty.
What If Your Model Has a Drain Plug?
Some snow blowers make it even easier. They have a small drain plug on the bottom of the gas tank. This changes how to drain snow blower gas tank a bit.
Look under your fuel tank. You might see a little bolt or plastic screw. That’s likely the drain plug. Check your owner’s manual to be sure.
Place your gas can directly under this plug. You might not need the tubing for this method. The fuel will drip straight down into the container.
Use the right tool to loosen the plug. Often it’s a simple wrench or screwdriver. Turn it slowly and be ready for fuel to start coming out.
Let all the gas drain out completely. Once it stops dripping, tighten the plug back up. Make sure it’s snug so it doesn’t leak later.
This method is very clean. There’s less chance of spilling gas on the engine or your hands. If your machine has this plug, use it.
Running the Engine Dry (The Alternative Method)
There’s another way people use. It’s called running the engine dry. You don’t physically drain the tank. Instead, you let the engine use up the fuel.
Here’s how it works. You start the snow blower and let it run. It burns the gas in the tank and the carburetor bowl. The engine stops when it runs out of fuel.
This method is okay for some. But I don’t think it’s the best way for how to drain snow blower gas tank. Let me tell you why.
It leaves a tiny bit of fuel in the carburetor bowl. This small amount can still evaporate and leave gunk behind. It’s not a complete drain.
You also run the engine without a load for a long time. This isn’t great for it. Engines like to work, not just idle.
If you choose this method, do it outside. The exhaust will be smoky at the end. Make sure you have good ventilation.
For a sure clean, I say drain it manually. But if you’re in a real pinch, running it dry is better than doing nothing at all.
Disposing of Old Gasoline Safely
You’ve got a can of old gas now. You can’t just pour it down the drain or on the ground. You need to get rid of it the right way.
Check with your local waste management authority. Many towns have hazardous waste collection days. They take old gasoline, paint, and other chemicals.
Some auto parts stores also take old fuel. Call around to see if any near you offer this service. It’s often free or very cheap.
You can mix a small amount of old gas with fresh gas in your car. The car’s large tank dilutes it, and the engine can burn it. Only do this if the gas looks and smells okay.
Never burn old gasoline in a fire pit or stove. It can flare up and cause a big fire. Gasoline vapors are very explosive.
The Environmental Protection Agency has guidelines for household hazardous waste. Proper disposal protects our water and soil. It’s the responsible thing to do.
Common Mistakes to Avoid
I’ve seen people mess this up. Let’s go over the big mistakes so you can skip them. This will make learning how to drain snow blower gas tank much smoother.
Don’t use a container that isn’t meant for fuel. A plastic water bottle can melt from the gasoline. Use a proper gas can every time.
Avoid creating sparks. Don’t smoke or use power tools near the gas. Fuel vapors can ignite from a single spark.
Don’t forget to turn the fuel valve off before you start. If you don’t, gas will keep trying to flow as you disconnect the line. It makes a big mess.
Avoid rushing the job. Take your time and be careful. Spilled gas is slippery and smelly. It’s also a fire risk.
Don’t skip cleaning up spills. Use cat litter or sand to soak up any gas on the ground. Then dispose of that material as hazardous waste too.
Finally, don’t think you’re done after draining. There’s one more important step for storage. We’ll cover that next.
After Draining: Preparing for Storage
The tank is empty. Great job. But you’re not quite done. You need to prep the snow blower for its long summer nap.
Start the engine and let it run for a minute. This burns the little bit of fuel left in the carburetor. It helps dry out the system.
Once the engine stops, pull the spark plug wire off. This is a safety step. It prevents the engine from accidentally starting while in storage.
Give the whole machine a good cleaning. Hose off any salt, dirt, and old snow. Let it dry completely before you put it away.
Check the oil level and condition. Change it if it’s dirty or if it’s been a year. Fresh oil protects the engine internals while it sits.
Lubricate any moving parts. The auger shaft, drive controls, and wheel axles might need a drop of oil. This keeps them from rusting or seizing.
Store your snow blower in a dry place. A garage or shed is perfect. Cover it with a breathable cover to keep dust off. Now you’re truly done.
What About Fuel Stabilizer?
Some folks swear by fuel stabilizer. They add it to a full tank of fresh gas and run the engine. The idea is to keep the fuel system treated all summer.
It can work. A good stabilizer can keep gas fresh for up to a year. This is handy if you hate the draining process.
But you must use it right. Add the stabilizer to fresh gas in your gas can first. Then fill the snow blower tank with this treated fuel.
Run the engine for five minutes. This circulates the treated gas through the whole fuel system. It coats the carburetor internals.
The Consumer Reports guide to small engine care mentions both methods. Draining or stabilizing are both accepted practices for off-season storage.
My personal choice is still to drain. I like knowing the tank is empty. There’s
