Yes...filters to use primary 30 microns (I use R 20P 30 micron)
secondary 10 microns (yanmar # 104500-55710)
Above are specs as per Mack Boring a large yanmar distributor.
Instructions how to change racor replacement element are printed on side of element.
I have used the screwdriver and pound method to remove ring
from secondary filter but as of late I use a pair of slip joint tongue
and groove plyers or can use a filter or belt wrench if will fit.
Can use filter or belt wrench for racor element as well.
Must bleed system after changing filters.
Hope this helps,
