How to Replace Gas Lines on a Weed Eater

Drain all remaining fuel from the tank into the approved fuel container. Start up the Weed Eater and let it run until all of the gas burns out of the lines and the carburetor. Switch the choke lever up into the closed position.

Unhook or unscrew, depending on model, the air filter box's cover. Pull the foam element out of the box. Unscrew, if necessary, the screw holding the box to the carburetor.

Unhook both gas lines from their elbow connectors on the carburetor using the needle-nosed pliers. Reach into the tank with the metal hook and draw the hose and filter towards the tank opening. Grab the fuel hose and pull it, along with the filter, out of the Weed Eater.

Cut off a replacement section of fuel tubing, about 8 to 10 inches long. Cut a diagonal taper at one end. Push the tapered end through the hole near the carburetor. Continue pushing the line until it reaches at least 4 inches into the tank. Cut off the tapered end and push the nozzle of the replacement fuel filter into the fuel hose.

Repeat the same process for the second fuel hose. Unscrew, if necessary, the primer bulb and lift it off the engine. Pull out the secondary or return fuel line using the pliers. Cut off the necessary lengths of fuel tubing for the return fuel lines. Push these lines through the hole in the carburetor, and the hole in the tank, respectively.

Attach all of the fuel hoses to their connecting points, two on the carburetor, and, if applicable, two to the primer bulb.
