You need to drain the tank and carburetor – this is the best way to get old gas out of a snow blower. I’ll show you the simple steps to do it right and get your machine running again.
Old gas turns into a sticky mess inside your engine. It clogs up the small parts and stops fuel from flowing. Your snow blower won’t start when this happens.
I’ve fixed this problem many times over the years. It’s a common issue after summer storage. The good news is you can fix it yourself.
This guide will walk you through the whole process. You’ll learn how to get old gas out of a snow blower safely and for good.
Why Old Gas is a Big Problem
Gasoline doesn’t last forever. It starts to break down after about 30 days. This process is called oxidation.
The lighter parts of the gas evaporate first. What’s left behind is a thick, gummy substance. This gunk is terrible for small engines.
It clogs the tiny passages in your carburetor. Fuel can’t get to the engine to make it run. That’s why your snow blower acts dead.
According to the U.S. Environmental Protection Agency, proper fuel management prevents pollution. Getting rid of old gas the right way helps the environment too.
Leaving bad fuel in the tank all summer guarantees problems. You’ll face a tough repair job when winter comes. It’s much easier to deal with it now.
Learning how to get old gas out of a snow blower saves you money. You avoid costly trips to the small engine repair shop. A simple drain can fix everything.
What You Need Before You Start
Gather your tools and supplies first. This makes the job go smoothly. You don’t want to stop halfway through.
You’ll need a few basic items. Get a siphon pump or a hand pump from the auto parts store. You also need a fuel-safe container for the old gas.
Have some clean rags ready for spills. A pair of pliers and a screwdriver helps too. You might need to disconnect a fuel line.
Get a fresh can of gasoline for later. You’ll want to put new fuel in after the clean-out. Use ethanol-free gas if you can find it.
A fuel stabilizer is a smart addition. It keeps your new gas fresh for months. Add it to every tank from now on.
Wear safety glasses and gloves. Gasoline is nasty stuff on your skin. Work in a well-ventilated area like a garage with the door open.
Having everything ready is the first step to learn how to get old gas out of a snow blower. It turns a big job into a series of small, easy tasks.
Step-by-Step: Draining the Fuel Tank
First, make sure the engine is completely cool. Never work on a hot engine near gasoline. That’s a major fire risk.
Locate the fuel shut-off valve if your machine has one. Turn it to the “off” position. This stops gas from flowing to the carburetor.
Place your empty gas can on the ground next to the snow blower. It needs to be lower than the fuel tank. Gravity helps the siphon work.
Insert your siphon pump tube into the tank. Put the other end into your disposal can. Pump the siphon to start the flow.
Let all the old liquid drain out. You might need to tilt the machine slightly. Get every last drop you can.
This is the core of how to get old gas out of a snow blower tank. Removing the bulk of the bad fuel is the most important step. The tank must be empty.
Wipe up any spills with your rags right away. Old gas leaves a smelly stain. Cleanliness makes the next steps easier.
How to Get Old Gas Out of a Snow Blower Carburetor
The carburetor is where gas turns into a fine mist for the engine. Old fuel leaves gummy deposits inside it. These deposits block the small jets and passages.
First, locate the carburetor bowl. It’s a small, round metal cup under the carburetor. There’s usually a single bolt holding it on.
Place your gas can underneath the bowl. Use your wrench to loosen the drain bolt slowly. Be ready for fuel to drip out.
Let the carburetor bowl drain completely. You might see dark, syrupy liquid come out. That’s the bad gas you need to remove.
Some models have a drain screw on the bottom of the bowl. Others require you to remove the bowl entirely. Check your owner’s manual for the right method.
This step is critical to truly learn how to get old gas out of a snow blower. The carburetor holds fuel even after the tank is empty. You must drain both.
Once it’s drained, tighten the bolt back up. Don’t over-tighten it. You could strip the threads on the soft metal carburetor.
Cleaning the Fuel Lines and Filter
Old gas leaves residue in the fuel lines too. These are the rubber hoses that connect the tank to the carburetor. They can get gunked up inside.
Follow the line from the tank to the carburetor. Look for a small fuel filter along the way. It’s often a clear plastic cylinder with a paper element inside.
Use your pliers to pinch the clamps on the fuel line. Slide them back so you can disconnect the hose. Have your rag ready for drips.
Remove the old fuel filter. It’s a cheap part that you should replace every season. A new one costs just a few dollars.
Blow through the fuel line to check for blockages. You should feel little resistance. If it’s completely blocked, you may need a new line.
Replacing the filter is part of knowing how to get old gas out of a snow blower completely. A clean fuel system starts with a clean filter. It’s an easy win.
Connect the new filter and reattach the lines. Make sure the clamps are tight. You don’t want any fuel leaks when you start the engine.
What to Do With the Old Gasoline
You can’t just pour old gas down the drain. It’s hazardous waste and bad for the environment. You need to dispose of it properly.
Check with your local recycling center or landfill. Many have special days for household hazardous waste. They’ll take your old gasoline for free.
Some auto parts stores also take old fuel. Call ahead to ask about their policy. They might charge a small fee for disposal.
Keep the gas in its clearly labeled container. Store it in a cool, dry place away from your house until disposal day. Never store it near a heat source.
The U.S. Department of Energy provides guidelines for fuel storage and disposal. Following these rules keeps you and your community safe.
Proper disposal is the final step in how to get old gas out of a snow blower. You’ve solved your problem without creating a new one. That’s responsible ownership.
If the gas is only a month old, you might be able to reuse it. Mix it with fresh gas in your car’s tank at a 1:10 ratio. The fresh gas will dilute the old stuff.
Refilling with Fresh Fuel and Stabilizer
Now for the good part. It’s time to put fresh, clean gas in your machine. This will bring it back to life.
Use ethanol-free gasoline if possible. Ethanol attracts water from the air. This water causes corrosion and more fuel problems.
Add a fuel stabilizer to your gas can first. Then add the fresh gasoline. This mixes the stabilizer in thoroughly as you pour.
Fill your snow blower’s tank about ¾ full. Don’t overfill it. Leave some room for expansion in changing temperatures.
Turn the fuel valve back to the “on” position if you turned it off. Let the fuel flow through the lines for a minute. It needs to reach the carburetor.
This fresh fuel is the reward for learning how to get old gas out of a snow blower. Your machine will thank you with easy starts and smooth running.
Run the engine for a few minutes after refueling. This circulates the stabilized gas through the entire system. It also burns off any remaining cleaning residue.
How to Prevent This Problem Next Year
Stop the cycle of bad gas for good. A little prevention saves you from this messy job next winter.
Always add fuel stabilizer to your gas can. Do this before you even fill your machine for the first time. It becomes a habit that way.
Run the engine for five minutes after adding stabilized fuel. This gets the treated gas into the carburetor bowl. It protects the entire fuel system.
At the end of the season, run the tank nearly dry. Then add a small amount of fresh, stabilized gas. Run the engine again to circulate it.
According to the Consumer Reports guide to small engine care, stabilized fuel can last up to two years. This means your snow blower is always ready.
Store your machine with an empty or stabilized-full tank. An empty tank prevents old gas problems. A stabilized-full tank prevents rust from moisture inside.
Knowing how to get old gas out of a snow blower is useful. Knowing how to prevent it is even better. Good habits keep your equipment running for years.
Common Mistakes to Avoid
People make a few key errors when dealing with old fuel. I’ve seen them all in my years of fixing small engines.
Never try to start the engine with old gas still in it. You’ll just suck more gunk into the carburetor. This makes the clog worse.
Don’t use starting fluid as a shortcut. It can damage engine components. It also doesn’t solve the underlying fuel problem.
Avoid mixing old gas with new gas in the snow blower. The old stuff contaminates the fresh fuel. You’ll be back to square one quickly.
Don’t forget to drain the carburetor bowl. Draining just the tank leaves bad fuel in the most critical part. You must get it all out.
Skipping the fuel filter replacement is a false economy. A new filter is cheap insurance. It keeps your clean fuel system actually clean.
These mistakes undermine your work on how to get old gas out of a snow blower. Do the job right the first time. You’ll save time and frustration later.
Write down the date you winterize your machine. Put a note right on the snow blower. This reminds you what you did and when.
When to Call a Professional
Most old gas problems are fixable at home. Sometimes, though, you need expert help. Don’t be afraid to ask for it.
If you’ve drained everything and the engine still won’t start, the carburetor might need a rebuild. Gummy deposits can weld internal parts together. This requires special tools and knowledge.
Major fuel leaks after reconnection are a safety issue. A professional can replace damaged lines and seals properly. Your safety is worth the service call.
Very old gas can turn into a solid varnish. This might require ultrasonic cleaning of the carburetor. Most home workshops don’t have this equipment.
The Occupational Safety and Health Administration has guidelines for safe fuel handling. If you’re uncomfortable at any point, stop and call a pro.
