1991 f-350

Alright so I got my 1991 7.3L IDI about 4 months ago and the guy I bought it from recently replaced the entire fuel system. Truck had absolutely no problem. Fast forward a few months and I decided to do a full service including engine oil, transmission oil, new transmission filter and oil filter. My problem started when I noticed a small diesel leak on one of my caps. I decided to change all return lines, caps and o-rings myself. Then the hard start problem has been happening ever since. Because if I this I feel that the air intrusion problem is on my return lines or caps. I feel like my problem is so inconsistent, at first I got it to start up every time for a few days in a row, now I can get it to sit for maybe 2-3 hours at most sometimes and it’ll start. Bought the kit from Amazon and caps were loose, so I ordered a better kit and installed it. There’s no diesel leaks from the caps or injectors but I still have the hard start problem after I bleed it and it dies. Need my truck back up and running any suggestions would be much appreciated.
For reference I don’t know much about this engine it is also my first diesel truck.
