I have a diesel 2010 crawler loader, and need to change the fuel filters as they haven't been changed since I purchased it (I know, bad of me)

I noticed from my hardcopy parts manual that two different parts were used for the filter filter head assembly- the early serial number range was AT 15065 T and the late (after 42,000) was AT 17389 T. Based on the mounting bolts for the head assembly (the two bracket bolts are spaced apart rather than close together) it would appear that I have the earlier setup which is consistent with some of the other parts on the crawler.
However the part number on my fuel filter head is different than either presented above (as best as I can read through the age and grime it is T 13263 T). I could not find it in the JD parts lookup.
Is this a replacement head for screw-on filters? I haven't taken the filters off so don't know for sure. if not, what filter replacement numbers am I looking for?
Thank you in advance
