This tractor appears to have correct fuel filter set-up.  If anyone knows where I might find them, please let me know. 

Thanks, Glenn

Hi Glenn, The 1st primary filter p/n is 1006543m91, the 2nd primary is 1005435m91,The
secondary (self enclosed) is 767900m91 is the same as many Olivers 77-770 etc and
a Case IH p/n is A 57228. The others (or all) should be able to be crossed from these
p/n's to something accessibleby a parts house.  Good luck, Chuck

 Glenn , Try  NAPA  3104,3113,and 3191.
I just got a set from them for a 33D. It should be the same. Dennis

Thanks, Chuck and Dennis for your responses.  This is what I currently have....not a factory set-up for sure, but certainly a clean look.  To go back to the factory set-up would mean having to locate every item on page 92 of the Parts List book.
