We have a O-320 in our 9A. I planned to use one of the Napa automotive filters I have read some use. On first oil change I discovered our oil filter mount takes a male threaded oil filter (i.e. the mount is threaded female).
I understand the female mounts were made to insure a bypass filter was used with that motor; is this correct? In any case, the Napa filter I planned to use is a bypass filter from what I have read.
So, how does one convert the oil filter mount to male?
