Exmark 120-4370  Fuel Line

The purpose of the Fuel Line, or Fuel Hose, is to allow gas to flow from the fuel tank to the engine. Over time, damage from heat, wear, debris in the tank, and chemicals can cause the fuel line to leak or become brittle and crack. The length of the line varies based on the equipment. Bulk line is often sold by the inch, so you'll want to measure the old line to ensure the replacement will fit correctly. For easier installation of a carburetor fuel line, add some oil to the end of the line to help it slide.
