Del Lorto PHM40 Carburetor Float Bowl Plug from a 1990 Husqvarna WXE510.
Bike's build date of June/1989, frame vin code is an L, so frame says it's a 1990 model. Compare pictures to the part you need to confirm the part is correct, not a lot of cross references available for this bike. Good useable part. Removed from a good running bike. Dirty as seen in picture. Comes as pictured.
