Grommet V470001140

This is an authentic OEM sourced item that is designed for use with Shindaiwa gas powered trimmers. The purpose of this tube is to deliver the fuel from the tank into the carburetor. When you press the primer bulb, it will purge all the air out of the carburetor and fill its chambers with fuel. The excess fuel is then forced back into the tank through the return line. Over time these lines tend to become brittle and may crack eventually requiring replacement. Keep in mind this high-quality item is made of durable rubber and is sold individually.
