If you're wondering where the fuel filter is in your Craftsman snow blower, it's important to note that some older snow blowers may not have one. Fuel filters are usually found in the fuel line, and they prevent dirt, gum, and varnish from entering the carburetor. If your snow blower is acting up, it may be due to a clogged fuel filter, in which case you may need to replace it.

What You'll Learn
Fuel filters are rarely the problem
Although fuel filters are important, they are rarely the cause of problems in snow blowers. Snow blowers are often left sitting for long periods of time without being used, and this can lead to issues with the carburetor.
As engines sit, fuel left in the carburetor can turn to gum and varnish, causing blockages in the small passageways and jets. This can result in the engine not running at full power, or dying when the choke is turned off. In this case, the carburetor must be removed and cleaned with carburetor cleaner, and the small holes and passageways blown out with compressed air.
It is also important to ensure that the gas can and tank are clean, as dirt can cause issues. Additionally, it is recommended to purchase fuel from well-known stations, as discount stations may sell fuel that is almost 30 days old and already stale.
While fuel filters are not usually the issue, it is still important to change them at least once per season, as per the owner's manual. This can help prevent problems and ensure the snow blower runs smoothly.

Carburetor issues
As engines sit, fuel that is left in the carburetor can turn to gum and varnish, causing blockages in the small passageways and jets in the carburetor. This can be fixed by removing the carburetor from the engine and cleaning all parts with carburetor cleaner. It is important to ensure that all small holes and passageways are cleared of debris and varnish, and that all non-metallic parts are removed, as the carburetor cleaner will cause them to disfigure and decompose.
If the carburetor is extensively corroded or varnished, it may be necessary to replace the carburetor assembly. This can be done using manufacturer-approved snowblower replacement parts.
To prevent carburetor issues, it is important to use fresh fuel and to avoid purchasing fuel from "Discount" stations, as the fuel from these stations may already be almost 30 days old when purchased. It is also recommended to use a fuel filter to prevent dirt, gum, and varnish from entering the carburetor.
For Craftsman snow blowers with a Briggs & Stratton engine, carburetor replacement parts can be purchased on Amazon or eBay.

Fuel type and age
The fuel type and age play a crucial role in the performance and maintenance of your Craftsman snow blower. Here are some essential considerations:
Fuel Type
Craftsman snow blowers typically use gasoline or petrol as their primary fuel source. It is important to use fresh unleaded gasoline with an octane rating of 87. While higher-octane fuels are available, they do not offer any additional benefits for snow blowers due to the low compression of their small engines. Using a higher-octane fuel will not improve starting or performance and is generally considered a waste.
Additionally, today's gasoline often contains ethanol, which can quickly turn to "junk and garbage" due to the breakdown of organic compounds in the fuel. This can cause issues with the carburetor, leading to restricted or plugged passages. To avoid this, consider purchasing fuel from well-known stations, such as Shell, BP, Sonoco, or Phillips 66, as they are less likely to sell stale fuel.
Fuel Age
It is essential to use fresh fuel in your Craftsman snow blower. Gasoline should not be left in the carburetor for extended periods, as it can turn to gum and varnish, causing operational issues. Any gasoline left in a gas can for more than 30 days should be discarded, as it may have already started to deteriorate.
To prevent fuel-related problems, it is recommended to change the fuel filter at least once per season. This will help ensure that your snow blower runs efficiently and reduce the risk of carburetor issues caused by stale fuel.
Fuel Stabilizers
While fuel stabilizers are available, they may not be effective with today's fuels. The addition of ethanol to gasoline can accelerate the deterioration process, and fuel stabilizers may not be able to prevent the fuel from going bad. Therefore, it is crucial to prioritize fresh fuel and proper fuel management practices.

Gas tank and fuel can cleanliness
Keeping your gas tank and fuel can clean is essential for the proper functioning of your Craftsman snow blower. Here are some tips for maintaining optimal cleanliness:
Gas Tank Cleanliness
The gas tank in your Craftsman snow blower should be cleaned periodically to prevent the build-up of dirt, gum, varnish, and other contaminants. It is important to note that the fuel tank should only be removed and cleaned if it is dented, cracked, or damaged. Here are the steps to clean or replace your gas tank:
- Drain the fuel tank by removing the fuel line from the carburetor and emptying the fuel into a safe container.
- Use a product like Sea Foam Cleaner to flush the tank and remove any remaining residue.
- If the tank is damaged, remove the support bolts and lift it off the lower supporting brackets.
- Install a new, clean fuel tank and secure it with the bolts.
Fuel Can Cleanliness
It is important to use clean fuel in your snow blower to prevent issues with the carburetor and fuel system. Here are some tips for maintaining fuel can cleanliness:
- Purchase fuel from well-known stations such as Shell, BP, Sonoco, or Phillips 66. Discount stations may sell stale fuel that is already close to 30 days old.
- Do not store gasoline in a fuel can for more than 30 days, as it can turn to varnish and cause issues with your snow blower.
- Consider using a small fuel filter for your snow blower, especially if you notice any rust or sediment in the fuel tank.
By following these tips, you can help ensure that your Craftsman snow blower's gas tank and fuel can remain clean, which will contribute to the overall performance and longevity of your machine.

Fuel filter replacement
Fuel filters in snow blowers should be changed at least once per season. Here is a step-by-step guide on how to replace the fuel filter in your Craftsman snow blower:
Step 1: Drain the fuel tank
Drain the fuel from the tank or run the snow blower until the tank is empty. It is important to perform this step in a well-ventilated area.
Step 2: Disconnect the spark plug
Pull the spark plug wire up and off the plug.
Step 3: Remove the starter switch
Remove the mounting screws and pull the starter switch off the bracket. Let the starter switch hang by the electrical cord.
Step 4: Remove the carburetor
Remove the acorn nuts that secure the carburetor to the engine. Pull off the choke and throttle knobs.
Step 5: Install the new fuel filter
Follow the instructions in your owner's manual to install the new fuel filter. Ensure that you purchase a fuel filter that is compatible with your Craftsman snow blower model.
Additional Tips:
- It is important to keep your fuel tanks and gas cans clean to prevent rust and sediment buildup.
- Do not purchase fuel from "Discount" stations as the fuel may be stale or old, which can cause issues with your snow blower's engine.
- If your snow blower won't run at full power and dies when you turn the choke off, the issue may be related to the carburetor rather than the fuel filter.
