Photo of box says it fits handyman #113179150. That's not true. This unit cannot be attached to the engine mounting bolt and will fall into the trash can. The original filter had a flat top and a wing nut that attached it to the motor housing. This assembly has a raised male stud and a pressure cap that does not attach to the motor housing stud. [See photos]. Since I changed the filter 4 or 5 years ago, I didn't notice any difference in design in the product photo. Guilty.
