Yes, you can do it yourself – learning how to remove old gas from snow blower is a key skill for winter upkeep. It’s a simple job that keeps your machine running great when you need it most.
Old gas left in the tank over summer turns into a gummy mess. This gunk can clog the carburetor and fuel lines. Your snow blower won’t start when the first storm hits.
I’ve dealt with this problem many times. It’s a common issue for seasonal gear. The good news is the fix is pretty easy.
This guide will show you the safe way to do it. I’ll cover all the steps from start to finish. You’ll have a clean fuel system ready for winter.
Why You Need to Remove Old Gas
Gasoline doesn’t last forever. It starts to break down after about 30 days. This is the main reason you need to learn how to remove old gas from snow blower.
The ethanol in modern gas attracts water from the air. This water mixes with the fuel and causes problems. It can lead to rust inside your metal tank and fuel lines.
As gas gets old, it forms varnish and gum. These sticky residues clog the small parts in your carburetor. A clogged carburetor means no fuel gets to the engine.
You’ll know you have bad gas if the engine won’t start. It might sputter and die. Sometimes it smells sour or looks darker than fresh fuel.
The US Forest Service notes proper fuel care for outdoor power tools. Stale fuel is a top cause of small engine failure. Taking care of it saves you money on repairs.
Learning how to remove old gas from snow blower prevents these headaches. It’s cheaper than fixing a carburetor. It also saves you time on a snowy morning.
What You’ll Need for the Job
Gather your supplies before you start. You don’t want to stop halfway through the job. Most items are common things you already own.
You need a siphon pump or a hand pump. This is the main tool for how to remove old gas from snow blower. A simple bulb siphon from an auto store works great.
Get a proper fuel container. Use one made for gasoline storage. Never use milk jugs or other random bottles.
Have some clean rags ready for spills. You’ll also want a funnel for adding new gas later. A pair of safety glasses is a good idea too.
For the last bit of old fuel, you might need a wrench. Some machines have a drain plug on the carburetor bowl. Check your owner’s manual for your model’s details.
Work in a well-ventilated area. Your garage with the door open is perfect. Keep any sparks or flames far away from the work zone.
Step-by-Step Removal Process
First, move your snow blower to a flat, open space. Make sure the engine is completely cool. You don’t want to work on a hot machine.
Place your empty gas can on the ground next to it. The can needs to be lower than the snow blower’s fuel tank. Gravity helps the siphon work better.
Insert the siphon tube into the fuel tank. Push it all the way to the bottom. The other end goes into your empty gas can.
Pump the siphon bulb to start the flow. Old gas will begin moving from the tank to the can. This is the core of how to remove old gas from snow blower.
Keep going until the tank looks empty. Tilt the machine slightly to get the last bit from the corners. You want to remove as much old fuel as possible.
For the final drops, check for a drain screw. Many carburetors have a small bolt on the bottom of the bowl. Loosen this to drain any fuel stuck in the carburetor.
Dealing with a Stubborn Siphon
Sometimes the siphon won’t start easily. The fuel might not want to flow at first. Don’t worry, this happens to me too.
Try pumping the bulb faster for a few seconds. You need to create a strong suction to get it going. Once it starts, it should keep flowing on its own.
Make sure the tube in the tank is fully submerged in gas. If it’s sucking air, it won’t work right. Push it deeper into the tank’s bottom.
Check that your collection can is lower than the tank. The height difference is important for the siphon effect. Place the can on the floor if the blower is on a bench.
If you still have trouble, try a different type of pump. A hand pump with a squeeze bulb often works better than a simple tube. You can find these at any hardware store.
The key to how to remove old gas from snow blower is patience. Take your time and don’t force anything. You’ll get the old fuel out eventually.
Cleaning the Empty Fuel System
Once the tank is empty, you’re not quite done. There might be gunk left behind on the tank walls. This residue can cause problems later.
Add a little fresh gas to the empty tank. Just a cup or two is enough. Swirl it around to rinse the inside surfaces.
Use your siphon to remove this rinse gas too. Dump it into your waste fuel container. You might see dirty particles come out with it.
Consider using a fuel system cleaner. Add it to a small amount of fresh gas for a final rinse. This helps break down any remaining varnish.
According to Environmental Protection Agency, proper disposal of fuel waste is key. Don’t pour old gas or rinse fuel on the ground. Store it for proper recycling.
Let the tank air dry for a bit if you want. Or you can move right to adding fresh fuel. The main thing is getting all the old stuff out first.
Adding New Fuel Correctly
Now for the good part – putting in fresh gas. Use gasoline that’s less than 30 days old if you can. This ensures it hasn’t started to break down yet.
Consider using fuel stabilizer with your new gas. This additive slows down the breakdown process. It’s great for seasonal equipment that sits for months.
Pour the fresh fuel through a funnel to avoid spills. Don’t overfill the tank. Leave a little space at the top for expansion.
Replace the gas cap tightly. Wipe up any drips on the machine. Gas on the paint can damage it over time.
Prime the carburetor if your model has a primer bulb. Push it a few times to draw fresh fuel into the carburetor. This helps with starting after the fuel system work.
Now try starting the engine. It might take a few extra pulls to get the new fuel through. Once it runs, let it operate for a few minutes to clear the system fully.
Common Mistakes to Avoid
Don’t try to dilute old gas with new fuel. This is a common error people make. The old fuel still causes problems even when mixed.
Never siphon gas by mouth. It’s dangerous and tastes terrible. Always use a proper pump tool for how to remove old gas from snow blower.
Avoid working near any ignition sources. This includes water heaters, pilot lights, or electrical tools that could spark. Gas fumes are very flammable.
Don’t forget to dispose of the old gas properly. Your local waste facility likely has a collection day for hazardous materials. Many auto parts stores also take old fuel.
Skip the temptation to use a shop vacuum. Vacuums can create sparks inside the motor. This could ignite gas fumes with bad results.
Remember to check the fuel filter too. If your machine has one, replace it while you’re doing this maintenance. A clogged filter will cause problems even with fresh gas.
Prevention for Next Season
The best fix is not needing to do this job at all. With a little planning, you can avoid stale gas problems next year. It’s easier than learning how to remove old gas from snow blower every fall.
Add fuel stabilizer to your last tank of the season. Run the engine for five minutes to circulate it through the system. This treats the entire fuel line and carburetor.
Some people run the tank completely dry at winter’s end. This leaves nothing to go bad over summer. Check your owner’s manual to see if this is recommended for your model.
Store your snow blower with an empty or treated tank. Don’t leave untreated gas sitting for months. Either method works better than leaving raw fuel to spoil.
The Federal Trade Commission has tips on small engine care. Proper maintenance extends the life of your equipment. It saves you money in the long run.
Mark your calendar for fall maintenance. Make checking the fuel part of your yearly routine. A little work now prevents big problems later.
When to Call a Professional
Most times you can handle this job yourself. But some situations might need a mechanic’s help. Don’t risk injury or damage to your machine.
If the fuel lines are cracked or brittle, replace them. This might be more complex than a simple drain job. A pro can do it quickly with the right parts.
When the carburetor is already clogged from old gas, you might need a cleaning. This involves taking the carburetor apart. It requires special tools and knowledge.
If you see rust flakes coming out with the old gas, the tank might be corroded. A rusty tank needs professional assessment. It might need replacement or special treatment.
For electric start models, be careful around the battery. You don’t want to cause a short circuit while working on the fuel system. When in doubt, get help.
Remember, safety comes first. If any part of how to remove old gas from snow blower makes you nervous, call a small engine shop. They do this work every day.
