On my Universal M25, 1983 Catalina 30, I took apart my Facet fuel pump and cleaned the screen inside for the first time. I see a small dime size tapered magnet at the bottom. Is this there just to catch any metal dirt? Does it make a difference how it is installed? I assume it is big side down and in the center.I do not want to make a mistake and damage the pump. I also intend to repipe and run the fuel from the tank thru my Dahl filter BEFORE the Facet pump. Any help would be appreciated.
