How to replace the fuel lines in your Craftsman line trimmer

Replacing cracked or clogged fuel lines is a common repair that can restore proper fuel flow and engine performance. Start by disconnecting the spark plug wire and draining the fuel tank into an approved container. Use needle-nosed pliers to pull the fuel filter out of the tank and detach it from the fuel line. Remove the old fuel lines from both the tank and carburetor, noting how they're routed.

Feed new fuel lines into the tank and reattach the fuel filter to the smaller return line. Connect the new lines to the carburetor, reconnect the spark plug wire, refill the tank, and test the trimmer. For full step-by-step instructions, follow our detailed line trimmer fuel line replacement guide.

What to do when your Craftsman weedwacker runs rough

Old fuel is a common cause of rough engine performance. If gas has been sitting in the tank untreated, it may have absorbed moisture and won't ignite properly. Drain the tank and replace it with fresh fuel. You may also need to replace the fuel filter if it's clogged with debris.

Checking the fuel lines for cracks is another important step—damaged lines can restrict flow and cause sputtering. Preventive maintenance like a line trimmer tune-up can also improve engine performance. If rough running continues, the carburetor may need to be cleaned, rebuilt, or replaced.
