Lawn equipment that has spent time in cold weather storage could experience some problems. These problems may be related to improper maintenance or pest infestation. Small rodents are known for chewing on rubber and plastic. Unfortunately, the fuel lines for most small gasoline engines are composed of these types of materials. Replacing the fuel line for a Weed Eater will not take much time to perform. While you are at it, you may want to replace the fuel filter as well. The filter resides in the fuel tank and must be removed in order to replace the fuel line.

Things You'll Need

  • Gasoline container
  • Needle-nose pliers
  • New fuel line
  • New fuel filter (optional)

Video of the Day

Remove the old fuel from the gasoline tank. Pull the fuel fill cover from the plastic tank. Tip the tank into a gasoline container. Empty the tank of any remaining fuel.

Locate the fuel line connection on the carburetor. Pull the line from the connection using the needle-nose pliers.

Push the old fuel line through the small hole in the bottom of the fuel tank. Leave approximately one inch to two inches of the line exposed.

Tip the fuel tank over, so the filling hole is facing towards the ground. Shake the Weed Eater until the fuel filter appears at the fuel fill opening.

Grab the filter and fuel line with the jaws of the needle-nose pliers. Pull the line and filter from the tank.

Lay the old fuel line alongside the new fuel line on a level surface. Cut the new line to length with the cutter jaws on the needle-nose pliers, using the old fuel line as a template.

Insert the new fuel line through the small hole at the bottom of the fuel tank. Leave approximately two to three inches exposed. Shake the tank again. Grab the end of the hose with the pliers.

Install the new fuel filter on the end of the fuel line that is coming through the filling hole. Push the fuel line and filter back into the tank.

Pull the fuel line through the small bottom hole till the length of the exposed fuel line will reach the carburetor connection. Push the new fuel line onto the carburetor connector.

Tips & Warnings

  • Consult local disposal regulations concerning the disposal of old fuel and oil. In most areas around the country it is illegal to pour these items down any type of storm sewer or household drain.
  • Never expose any form of fuel to open flames. The fumes can immediately combust.
