Replacing a fuel filter on a Craftsman gasoline blower is rather simple. The filter helps increase the blower's power and keeps the motor from blowing up because there's no gas filtering through the motor. You will need only a Phillips screwdriver to replace the fuel filter in a few minutes.
Use a Phillips screwdriver to unscrew the blower's plastic casing on the side with the pull cord. Depending on the Craftsman model, there will be between four and six screws.
Pull the casing off the motor. Directly under the plastic gas tank is a small black hose. Follow it until you see a cylindrical piece protruding from the hose. This is the fuel filter.
Pop the hose off the filter. The filter will come out easily after you take off one side. Remember how the filter is positioned in the hose. Take a new fuel filter and place it where the old filter was.
Snap the plastic casing back on the motor.
Secure the casing by reinserting the screws and tightening them with the Phillips screwdriver.
