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

Kit includes seals and diaphragms to get my old used Danner AP-100 pump working again. I don't know how old this first pump is. I bought it used and it ran for two years before it stopped producing compressed air. Instead, I bought a new AR-100 pump. Redundancy is a good idea for my use case. Today I installed a set of parts and the old pump works like new. Very happy with the parts kit and solid pump. The instructions included exploded views of assemblies that needed new parts. The instructions provide helpful hints on how easy it is to mix up an assembly of parts. Unless you're mechanical, work slowly, be careful, and don't force anything. If it doesn't assemble easily, you probably have something wrong with me. The kit does not include the main housing gasket and two fibrous air filters under the pump housing. The kit includes a gasket for the pump housing. I want to replace all the seals and filters while disassembling the pump. But all the important parts are included.
