I need a new pool filter basket and I cannot seem to find any markings on the basket, filter cover or the like. The pump motor is a Magnetek 8-184981-21 if that helps at all. I figured it would be pretty easy to identify with the rectangular cover with 4 screws but I cannot seem to find any models like that. The pool was here when I bought the house so I don't have the original documentation. Any tips would be appreciated.
