Review on Enhanced Supreme (Danner) ASP14565 Diaphragm Replacement Kit for AP-100 Aquarium Air Pump by Vickie Kraus

Package includes most of the items needed for the restoration. My pump diaphragms are torn. The new diaphragms fit snugly and required some effort to reinstall. Keep the screws in order. The four holding the top of the case are the same size (but longer) than the ones holding the base. If you use the wrong size screws when assembling, the case will not assemble and you will have to remove each screw one by one and try to find the long ones. If you follow the instructions and make sure the diaphragms are fully installed, you'll have a nearly new pump. There are a few gaskets and filters that aren't included, but if you're careful they should still work.
