If I am planning to relocate my oil filter to ease access to the filter duing oil changes, what size should I tap the holes in the block to? I am planning drill and tap the oil holes on the block and use an NPT to 10 AN adapter and run 10AN braided lines to the remote filter to be mounted on the firewall.
Should I drill and tap it to 3/4 NPT or 1/2 inch NPT?
