74 Ford 3000 Pressure line blows out of fitting

I am hoping someone can help me, I am at my wits end. I got a pin hole in my hydraulic pressure line. I bought a new line (Part # D0NNH867D) When I received it I found that it didn't have the fittings on either end. I ordered 2 (FDS3714) fittings from yesterdays tractor. I put the fittings on the line and put the tractor all back together. The connection going into the sump has held fine with no issue, but the end going into the pump blew the line right out of the fitting. So I found a video on YouTube explaining that these cheap fittings that don't have the steel washer tend to not seal or leak so I bought 2 GR2117 because it was the only set I could find that had the steel washer. I put it all back together and this time it held for about 3 minutes before blowing the line right out of the fitting again. So fearing that I didn't get it back together just right I tried again. I put it all back together using a new fitting and made sure it was tight as I could humanly get it. It held for about 5 minutes and again blew the line right out of the fitting. I cannot get any fittings to hold the darn line in the fitting once the pressure has built up in the line. Please someone tell me there is a line assembly that has the end already on it or something that can hold my line in the fitting. PLEASE FOR MY SANITY! SOMEBODY HELP ME!
 
If the 3 point lift isn't doing any work then the pressure shouldn't be building like that. Does it have any remote valves with nothing connected that might not be centered properly?
 
yes, It has a loader on it. I have also have a post hole digger on the 3 point at the moment and it is raised so when the tractor is started and the system pressures up the 3 point raises the post hole digger.
But I raise or loader a few times and the line blows out of the fitting every time.
 
Those lines were not one of Ford's better ideas. I have messed with them a few times but it's been a dozen years now.
At the time I too was at wits end. Sold a tractor and it kept blowing out that fitting.
I fixed it 2 times after the sale - 45 miles from home. Grrr
If it hadn't held the second time I was going to try to convert it. Go to a big hydraulic shop and see if they had a fitting that would screw into the pump in place of that rubber/washer fitting. Convert it to a modern JIC fitting and double flare the tube to fit.
 
I had the same problem. I took the advice I received on this site and went directly to the local Ford dealer and bought the fitting from them. I have had no trouble with it since. I had some leakage recently but was able to tighten it up and the leak has ceased. If I encounter any more trouble at that end of the supply line, I'm going to do exactly what Dog (UltraDog, not the Bounty Hunter) said, have the pump end machined for a dang hydraulic hose!
