I am new to tractors and looking for some advise prior to opening her up. I have developed a leak what appears to be coming from the bottom of (2) of the 4 line nuts that go to pump under the tank. I dried her off then ran awhile and looks like its coming from between the nut and the case? The 7/8" nuts are tight- first thing I tried. Appears that they are original and may have never been off. Any ideas as to what is under the nut? O-ring or seal? Or is it a flared line? I will be looking at it this weekend and did not want to be too surprised. Hopefully easy fix. Also- the (2) that are leaking are on the rt. side if it matters.... Thanks in advance - Chris

you might have a fatigue crack in the pipe right at the edge of the flare, and you will have to remove to see
