I bought a new hydraulic pump from this site and it bolted up fine but when i went to hook up the lines all the ports were different sizes. i bought some adapters and the lines hooked up fine but the suction tube from the filter housing does not fit. I have a 2-155 that has this same pump and i understand that all the bigger tractors had this pump from the 1850 through the 135-55 tractors. I called the distributor and they told me i should go to a hydraulic shop and have a fitting made. I need help/advice from those of you that may have run into this problem and what you did to fix the issue.
