Plastic fuel lines for small engines will eventually break. When this occurs, the fuel line must be replaced to avoid hazardous leaks. Replacing a fuel line on a Poulan Weed Eater will not take much time. In fact, the process takes less than one hour. It may be a good idea to replace the internal fuel filter while you are replacing the line. The filter sets inside the fuel tank, and on the end of the fuel line.
Remove the cap from the fuel tank. Tip the engine over so the open fuel tank can empty into the gasoline container. Ensure that all the fuel has exited the small plastic tank.
Identify the fuel line. The small diameter plastic hose runs from the bottom side of the fuel tank, and into the carburetor. The small carburetor is located just under the muffler on the engine.
Pull the fuel line from the carburetor, using the needle-nose pliers. The hose fits over a small metal nozzle on the side of the carburetor.
Push the fuel line into the fuel tank, through the small hole on the bottom of the tank. Leave approximately 2 inches of the fuel line outside the tank.
Turn the engine over. Shake the Weed Eater. The small fuel filter will work its way to the opening on top of the fuel tank. Garb the end of fuel filter or the hose with the needle-nose pliers. Pull the assembly through the fuel fill hole.
Remove the fuel line and filter completely from the tank. Lay the old hose next to the new fuel line. Cut the new line to length with the pocket knife.
Push the end of the new fuel line through the small hole at the bottom of the tank. Leave approximately 2 inches of the hose on the outside of the tank. Turn the engine over. Shake the Weed Eater. Grab the end of the hose with the needle-nose pliers.
Pull the hose through the fuel fill hole. Insert the new fuel filter on the end of the fuel line. Stuff the assembly back into the fuel tank.
Pull the fuel hose back through the lower small hole, until the end of the line reaches the carburetor connector. Push the line onto the small metal nozzle.
Fill the Weed Eater with a fresh gasoline-oil mixture. Choke the carburetor to draw fuel through the new line. Start the Weed Eater.
