Need help with ford 2000!

[Collinford2000]

I was bushhoging with my grandpas 1973 ford 2000 diesel last summer and the back tires went down in a little ditch and the bushhog stayed up on the hill so I was stuck until I raised bushhog. Well after that the high pressure line going into the hydraulic pump blew out. So we pulled it up to the house and tightened the nut and it still blowed. I bought a new line and new nut and copper fitting that goes on the line and it still blew so we thought maybe it was a pressure relief valve problem so we took top cover off under seat and replaced hydraulic filter and one of the pressure relief valves and put it all back together and it still blows out around line going into pump about 5 seconds after starting. I’ve seen people on here discussing the same problem but nobody ever had an answer. If anyone knows anything it would be greatly appreciated because I’m not sure what else it could be.

Pics would help.

How did it blow apart? Was the fitting damaged and now why it no longer stays connected?

A picture would help. Do the lines, suction and pressure going across the bell housing,

have the hold down clip in place? #77
