Draining Fuel Lines: Snowblower Maintenance 101

how to drain fuel line snowblower

If your snowblower's engine won't start, it could be due to a clogged fuel line. This can be caused by the ethanol in regular fuel mixing with water that has seeped into the tank, resulting in corrosion and clogging. To prevent this, it is important to drain the fuel line and tank before storing your snowblower. This can be done by removing the lower plastic panel and exposing the fuel line, which can then be pulled off the fuel tank or carburetor. Alternatively, a siphon pump can be used to drain the tank.

Why draining fuel is important

Draining fuel from a snowblower is important for several reasons. Firstly, regular fuel contains ethanol, which, over time, can mix with any water that may have seeped into the tank, leading to corrosion and clogging in the engine. This can cause significant problems with the machine's performance and may even require a trip to the repair shop for a professional clean. Therefore, it is recommended to drain the fuel before putting your snowblower into storage to prevent these issues.

Additionally, failing to drain the fuel can result in stale gas, which can cause difficulties with starting the engine. This is because old or stale gas can "'gum up' the carburetor, making it harder for the engine to start. By draining the fuel and starting with fresh gas, you can help ensure that your snowblower starts up more easily and runs smoothly.

Furthermore, safety is a critical consideration when dealing with flammable substances like fuel. It is essential to select an outdoor location away from heating units, open flames, or any other sources that could ignite the fuel. By draining the fuel, you reduce the risk of accidental fires or explosions during storage or when the snowblower is not in use.

While some users have reported leaving fuel in their snowblowers without issue, it is generally advisable to follow the manufacturer's recommendations for proper fuel management and storage to ensure optimal performance and safety.

In summary, draining the fuel from your snowblower is important to prevent engine corrosion and clogging, ensure easy starting, and maintain safety during storage and non-use. By taking the time to properly drain and maintain your snowblower's fuel system, you can help extend the life of your machine and ensure it is ready for use when you need it.

How to drain fuel with a siphon pump

To drain fuel from a snowblower with a siphon pump, you must first select a suitable location. This should be outdoors, away from any sources of ignition, such as an open flame or heating unit. The location should be flat to minimise the risk of slipping, and you should ensure that the snowblower's engine is switched off and cool before you begin.

Next, you will need to obtain a siphon pump. These are commercially available for as little as $10-$15 and come in a variety of shapes and sizes, including manual and automatic pumps. Once you have your pump, you should familiarise yourself with its basic function. Siphon pumps work by manually squeezing a pump with one hand, which generates a pumping action. Two tubes extend from the pump: one is placed into the reservoir you are siphoning from, and the other is placed into the container you are siphoning into.

Before you begin, ensure you have a suitable container to catch the fuel in. This should be a closed container, such as a gas canister, rather than an open container like a bucket, to minimise the risk of spillage and exposure to fumes. Place the end of one tube into the fuel tank of the snowblower, placing the tube as deep into the tank as possible. Then, place the end of the other tube into your chosen container, positioning it at a suitable distance from the fuel tank.

Now, you can begin to siphon the fuel by manually pumping the device. You may need to pump a few times to get the fuel flowing. Once the fuel is flowing, you can continue pumping until the container is mostly full. To stop the flow of fuel, simply raise the end of the tube in the container to a level higher than the fuel in the tank. This will cause any residual fuel in the pump to drain back into the tank. Finally, remove the siphon pump from the tank, being careful to avoid any spillages, and seal the container. You may then need to clean your siphon pump before storing it—consult the instructions provided with your pump for more information.

How to drain the last bit of fuel

To drain the last bit of fuel from your snowblower, you will need to use a siphoning method. Firstly, make sure your snowblower is switched off and the engine is cool. You should also select a safe location outdoors, away from any heating units, open flames, or other sources of ignition.

Next, you will need to obtain a siphon pump. These are available to purchase from hardware stores or online. Alternatively, you can use a turkey baster or a hand bulb-primer siphon. Once you have your siphon, place one end of the tube into a container that will catch the fuel. Then, place the other end of the tube into the fuel tank of your snowblower. You may need to use a stainless-steel drinking straw to help guide the tube into the tank.

Now, squeeze the pump on the siphon to begin draining the fuel. You may need to tilt your snowblower slightly to help the fuel accumulate in one area of the tank. Continue pumping until you have removed as much fuel as possible.

Finally, to get the last bit of fuel out, replace the cap on the fuel tank, and start the engine. Let the engine run until it shuts off by itself due to a lack of fuel. This will ensure that any remaining fuel is used up.

How to drain fuel without a pump

To drain fuel without a pump from a snowblower, you will need to select a suitable location outdoors, away from heating units, open flames, and other potential ignition sources. The location should be flat to minimise the risk of slipping, and you should place a pan or container to catch the drained fuel at a suitable distance from the snowblower.

Turn off the snowblower and allow the engine to cool. Then, remove the cap from the fuel tank. Depending on the model of your snowblower, you can either remove the lower plastic panel to expose the fuel line or locate the fuel filter. Once you have located the fuel line or filter, place a container underneath it to catch the drained fuel.

Now, disconnect the fuel line from the tank or carburetor, and allow the fuel to drain into the container. You can also blow compressed air into the fuel filler hole to force the fuel out. Alternatively, you can tip the snowblower onto its side and pour the fuel out through the filler hole, but this may result in some engine oil leaking out as well.

After draining as much fuel as possible, replace the cap on the fuel tank, start the engine, and let it run until it shuts off due to a lack of fuel. This will remove any remaining fuel from the engine.

How to prevent fuel line clogs

To prevent clogs in your snowblower's fuel line, it is important to maintain the fuel system. Fuel left in the tank for extended periods can cause the fuel lines to become gummed up, leading to blockages. To prevent this, ensure you use fresh fuel and avoid letting it sit for too long. If you need to store fuel, consider using a fuel stabilizer to extend its lifespan. Additionally, regular maintenance and cleaning of the carburetor and fuel system can help prevent clogs.

Another way to prevent clogs is to pay attention to the type of fuel you use. Some fuels may contain ethanol, which can break down and clog the fuel line. Using a higher-quality fuel with no ethanol or a small amount of premium fuel at the end of the season can help prevent this issue.

It is also important to keep the area you plan to use the snowblower on clear of any foreign objects, as these can cause clogs. Always inspect the area before using the snowblower and remove any potential obstructions.

Additionally, maintaining a consistent pace when using the snowblower can help prevent clogs. Operating the machine at a steady, even pace ensures the snow is processed quickly, reducing the chance of buildup and clogs.

Finally, using a non-stick spray or lubricant designed for snowblowers can help prevent snow from sticking and building up inside the machine. This type of spray is similar to cooking spray and can be applied to the augers and chute to keep the surfaces slippery and reduce the chance of clogs.
