Mike, I have confused myself. When I watched your video, you definitely talk about the filter being installed backwards. Just out of curiosity I went to the Donaldson site. The catalog drawings for the eco filters indicate the side port is the discharge, and the end port is the inlet. Hence my confusion. Can you help me find the literature that indicates it is the other way round?
