I have looked over my new to me 05 ranger Z20 its has a 10/04 225 hpdi engine with 60hrs. I cant find any external fuel filters in the rear compartments. Are there any that go on the engine? I am also going to change the hpdi filter screen and want to do the entire fuel system at one time. As far as I know the previous owner always used yamalube but no seafoam.
