While reading the article about building a better hipo motor in the February issue of MM a picture of a hand slipping on the filter housing of a Rotunda filter over a modern filter can be seen. (Page 38, top photo) Removing this cover from a reproduction filter has been discussed before but has anyone ever come up with a way to get these apart and reuse the outer "can" by slipping it over an modern filter? Seems simple enough but try as I might the reproduction Autolite filter I have will not separate. It is time to change oil and the ideal time to seperate the cover from the filter and reuse the can so if you have been successful at this trick, how did you do it and what was involved. Any pictures of this magic removal? Also I have always had a desire to know what type of filter is hidden within those reproductions. Speculation is a fl-1 Motorcraft, but does anyone know for sure?
