Pulled off a working 9000SX. We switched to a bucket less system so no need for these pumps. They heavy duty and will probably last longer than the edger itself. Attached photos. I didn't try to clean it but that is edger scurf from it being in use. Probably can get it nice and shiny with a little elbow grease.
You are getting two units. I only took a picture of 1 but you can see the other in the background.
