Help power steering leak won’t ever end.?

I have a 99 F150 with the 5.4 and the stock pump was starting to show its end of life. I got an remanufactured pump and originally got a line from Rock Auto. When I first put it on, it started dripping more than the last pump from the high pressure line to the pump. I took off the pump again and thought it just wasn’t tight enough so I tightened it more and put it back on. Leaked even worse from the high pressure line so I thought the line was toast and I got myself a Duralast line hoping 3rd time would be the charm. Put the new line on and sure enough, it’s leaking at a dripping rate. I’m out of ideas, I’ve removed the pump now 3 times and this is frustrating me. Is it the pump threads? I don’t know what to do and I can’t afford mechanic prices right now. Please someone tell me what I should do.
