How to replace a snowblower fuel line
This step-by-step repair guide shows how to replace the fuel line on a snowblower. The fuel line carries fuel from the gas tank to the engine. If the fuel line is cracked or damaged, fuel won't flow to the carburetor to start the engine. Replace a damaged or cracked fuel line with the manufacturer-approved snowblower part.
Use these steps to replace the fuel line on Craftsman, MTD, Murray, Troybilt, Husqvarna, Toro, Murray, Ariens and Noma snowblowers.
