This DIY repair guide shows how to replace the fuel filter on a snowblower. The fuel filter attaches to the fuel tank and screens out dirt and rust particles from gasoline. If the fuel filter is clogged, gas can't flow to the carburetor, and the snowblower might not start. Replace the fuel filter with the manufacturer-approved replacement part if it's clogged or damaged.
Use these basic steps to replace the fuel filter on common Craftsman, MTD and Murray snowblowers.
