This is a genuine OEM replacement part, it is sold individually.
The purpose of the Fuel Pick--Up Line with Filter is to provide fuel into the carburetor via the primer bulb.
The filter is situated inside the fuel tank,with the fuel line extending through an existing hole in the fuel tank.
It is then connected to the primer bulb which will purge the air out of the carburetor.
By pressing the primmer bulb it will fill the carburetor with fuel, once it is full the excess fuel will be forced back into the tank through the fuel return line.
Over time the fuel filter will be come clogged with debris and will have to be changed.
