This part fit my tractor perfectly. The problem with this part was how it was assembled. The intake elbow was a pressure fit part whereas it should have been cast. I installed the filter unit, ran it for about an hour and the intake elbow loosened and popped off the rest of the filter assembly spilling diesel all over the muffler system on my tractor! I ended up fixing the part with JB Weld to hold it together. Terribly designed part for $75.00! Not satisfied with this purchase!
