this weeks problem....
OEM bypass spin on filter adapter.805 OD
Jegs non bypass adapter.............810 OD 16 TPI
tried a thread file, no luck, thought there might be a burr
Put adapter on lathe, removed 5 thou. still a tight fit, but worked it back and forth with lube, seems to go all the way on

I think I can clock the adapter now, once I figure out location
