This is a picture of the two filters. As you can tell by the picture I punch a hole in the 14070 filter. It is confusing because of the manual I was looking at shows the white one in the picture as the suction. The yellow also has HST filter stamped on it. So I thought I punched the wrong filter.
in this manual page 78 it refers to the front most filter as the suction filter??? the service manual at least the one i have doesn't agree. but the number i gave you is correct for the rear most filter and it's placement so check it anyway. Kubota manuals are less than to be desired but it is all we have. the rear most filter is attached to the charge pump housing. so i guess i will refer to it as the charge filter from now on to hopefully avoid confusion. sorry also to note that i refer to the front as oriented from standing behind the machine and looking forward so the front would be nearest the front of the machine and the rear would be toward the rear of the machine.
