Thanks I’ll take a look, I really hope the fitting on the fuel rail isn’t messed up. Man I’m so stressed out from putting these injectors in. It’s been one problem after another.
I have repaired threads like that before with a fine hacksaw blade to clean out the crushed metal and restore the threads. Of course some metal thread will be lower/missing, but you might get it to thread properly again with a small amount of careful filing. That fitting doesn't need to be extremely tight, just enough to snug and seat the rubber o-ring (which desperately needs to be replaced based on your picture). The o-ring performs the gas sealing function and doesn't need a lot of compression to seal.

I’m going to try cleaning it up tomorrow. Someone on Ebay is selling both the lines for 85 bucks. But man that’s a lot of money for two small lines. Yeah that o ring is gone! I don’t even know how it was stopping fuel from leaking out. Do you happen to know what size o ring I’m looking for?
So here’s an update guys. I coughed up the 90 bucks and just bought the two lines off Ebay. I have the runners assembled. I have the injectors plugged in, turned the key to on. Heard the fuel pump prime, didn’t see any leaks. Is that the correct way to check for leaks? Waiting on my Plenum gaskets from Amazon today to have the rest installed. Now the problem I had before all this was. White smoke from exhaust, smelled like pure gasoline. Regulator had fuel in the vacuum line. I replaced that, changed the injectors also. Since oil smelled like gasoline. Now probably a dumb question. But should I change my spark plugs also while I’m at it?
How do you use that? Might be a dumb question, but how does it restore the threads?
Each side of the file has a different pitch or threads per inch. You pick the one that fits the thread pitch that you are working on. The file will guide in the good threads and overlap to the bad threads. It will cut the cross threaded bad threads back to match the original thread pitch. File around the OD of the bolt or fitting until it cleans up.

Reason: fix typo

You could at least pull a couple and check them. If it was running before, they're probably all right. Fuel fouling will usually burn off. You can also clean them with solvent like carb cleaner.
I would be more concerned about your comment that the oil smells like fuel. Oil will tolerate a little fuel dilution and it will mostly boil off when the oil warms up; but if you have too much gasoline in the oil, the oil doesn't lubricate so well. I've seen old carburetor engines run that were a quart over full from dilution in the dead of winter. That requires a prompt oil change.

Man I wish I knew about that a few days before. I might still go buy it and try it out.

Well it wasn’t a drastic amount. The oil was nowhere watery or anything like that. It just smelled a little like gasoline. And it was always in the markings of the dipstick. But yeah, it was a mess before I changed everything. My intake was just pouring gasoline out.
