Review on 🐠 Enhanced Supreme (Danner) ASP14525 Diaphragm Replacement Kit for AP-20 Aquarium Air Pump by Asia Turner

Bought to restore an AP-20 that had both diaphragms torn. There was an instruction manual in the kit (good) but the housing o-ring does not fit this pump model (bad). In addition, some other parts such as a spare filter and spare feet are not included. It comes with parts to convert other pump models so you still have parts. The pump is easy to convert. It took me about 20 minutes for both sides. Attached are photos of the original parts of low quality. Be sure to clean the two halves of the white plastic housing so that no dirt gets into the valves after the conversion. You can see the seal in my pump does not match the seal photo in the product description. The AP-20 pump body gasket has four holes, the gasket has two holes in the kit.
