Stihl is apparently stingy with info for their products, probably to increase revenue for their dealers. But with the item scale drawings I was able to spec a primer bulb for my FS76 string trimmer. Thanks Jack for the thought put into your website.

I received the right part It work well In my trimmer. Delivery time was fast. The price of the part was right, I thought shipping cost Of more than part cost was a little high. However The trip into town Would cost more than the shipping cost so I guess I got a good deal. Would order From this supplier again.
