This is a genuine Homelite replacement part.
It is sold individually.

By pressing the bulb it will purge the air from the carburetor.
Then fuel will come up from the fuel tank through the fuel line then into the carburetor.
The excess fuel will be forced back into the tank through the fuel return line.

Over time the primer will lose its elasticity or crack and need to be replaced.

    The primer bulb was exactly what I needed for my old string trimmer.
    The primer bulb was exactly what I needed for my old string trimmer. I've always had good luck with replacement parts that I've gotten through your website. My only complaint in this particular case is that the shipping cost seems too big for such a dinky little part that is mailed through USPS in a little baggie. Otherwise availability of the part and promptness of shipping is appreciated.
