Well....I got it back together using hoses rather than pipe. here is a picture of the pipe that split on me. I think it was worn from rubbing against the other pipe...it is tight under there.
Now for a question: I used a 2- 90 degree swivels and a 1/2 pipethread x 5/8 JCI for one of the hoses to be positioned better. One of the 90's came with the PTO system, the other I bought today at TSC. It is a 1/2 pipethread x 1/2 pipe thread . The 90 degree 1/2x1/2 pipethread is leaking. Should I have used paste or tape on that connection?
