HPOP line fitting O-ring concern
Another option would be to tap it to NPT pipe threads, then install an NPT to JIC adapter. Tapered pipe threads aren't the best in high pressure applications (JIC and SAE boss seals are better) but they work. I'd check with CNC Fab first, messing with the pump may put you out of a core refund, if you drill it larger than they would for their steel thread inserts. I'm seeing that the oil pressure can reach 3000psi, but I don't know how accurate that is. Be careful and make sure the fittings are rated properly. I suggest a new pump.
Back to the sealing discussion, how did the hollow copper sealing rings work out for you? https://www.ford-trucks.com/forums/1...per-a-try.html

The copper works like a champ. They're not hollow though, just plain copper sealing flat washers. I even went through and changed all the oil rail plugs, ICP, and whatever else I could think of at the time over to copper washers. They all hold fine even without the special chamfered fitting. I still in no way recommend the hoses from those folks, but the fittings look quality and am very pleased w/ them.

If those threads are stripped I would recommend against any repair while on the truck. The chance of aluminum slivers getting into the HPO is a big risk imo.
I would yank it without another crank and send as core for another HPOP of your choice.
So I'm cranking, and cranking, and cranking some more. New batteries AND new starter so I had optimal cranking efficiency, but it just would not fire. I was concerned that his set up was allowing just too much air in, but I also thought about how the previous night (despite my earlier cautioning
) he had accidentally disconnected two of the three wires that go into ICP (this being prior to the ICP meeting it's maker a short time later, see attached pic) and there was a chance that he had gotten them mixed up when reconnecting them. So I told him to unhook the sensor, and gave her another crank.... after about 10 seconds it fires up! Yes!!
Since I have no idea how well the fitting is holding or how much oil I might be spewing, I mobbed home as fast as I could...which, without the ICP sensor was pretty brutal. I had to floor it just to make it up the hill that I live on, which of course was making me cringe watching the RPM rise over 2,500, but low and behold I made it!! Even better, the fitting held relatively well! I mean, it was definitely leaking, but no 3,000psi oil blowout all over my engine, so I was pretty stoked!
Starting fresh the next day, I siphoned all the oil out of the HPOP then pulled the 18mm bolt from the back of pump to drain rest of oil out of pump... sweating the entire time obviously, just dreading what I was going to find out regarding the fitting threads.
For the record, I really hated the idea of having to buy/install a brand new pump, but I hated the idea of someone attempting to use helicoil to make new threads even more... just the thought of metal shavings in my HPOP was giving me massive anxiety. 
With the pump and fittings now completely drained/free of oil, I surveyed the situation... and low and behold, they were both in pretty damn good shape! At this point I'm starting to happily conclude that it was just the lousy aftermarket fitting with it's shallow threads that was damaged, not the pump! Confirming what I was already planning on doing: yanking everything out except the crossover hose and reinstalling my old hoses with Loctite on them and hoping for the best!
So after applying the old fittings with Loctite on them, I decided to give them 30 hours to cure/set in before buttoning everything back up and refilling HPOP. Took the time while I was waiting to rewire ICP properly (made a video for YouTube to show how to wire it properly if wires were mixed up, since to my knowledge there wasn't one) then finally the time came to crank. After about 20 seconds total (two 10 second intervals) she fired up and was purring like a lion! Best of all, not a drop of leaking oil to be found!
In the two weeks since I have had ZERO issues and truck is running great! Talk about a relief! Knocking on wood for it to stay that way, but for the moment I am just enjoying my seemingly good luck! Sorry about the novel, but I wanted to give the entire scenario it's due. Thank you to everyone for all of your comments and suggestions, I am extremely thankful that a site like this exists!

Da da da duhduh!
Oldies back in action!
Oh and for the record when in a bind you can plug the offending port on the pump and limp the truck home on half an engine. Go ahead ask me how I know. Actually there's a thread around here somewhere documenting that little adventure.

I hope she never sees this thread because she will legit f****ng murder me, real talk

I definitely considered just plugging the port, but I was concerned about putting too much pressure on the other side... good to know in the future though!
I had a feeling the crossover crap was BS...
