Hi.
- The fuel rail ends use O-Ring Boss Radius "ORB" fittings ("DO NOT" Use Teflon Tape on Threads of ORB fittings.) and are not AN or NPT threaded fittings, ORB fittings can be removed and reinstalled hundreds of time without issues. The O ring seals the fittings, so you don't overtighten.
- The Fuel line if Steel Braided, the End Fitting "SOCKET" Does not tighten all the way down, if so it most likely will leak from over torquing Socket to fitting and have to be replaced. If they are Push to Lock install procedures are different. Also, You don't use Nylon Braided line Fitting/Sockets on Steel Braided line unless they state they can be used.

The line fitting that was leaking was snug. I snuggled it up more, it still leaked.
The plug that was leaking was an Allen head 'button' plug on top of fuel rail. Not what is shown in your post. It is incredibly soft metal, presumably designed to distort in order to resist pressure of fuel injection. However, the metal is so soft that it rounded out very easily.

It's probably a -6 orb. I would remove. If threads are crossed I would remove fuel rail before I start my engine. Buy the right thread tap and clean it up. I would buy a new ORB plug which comes with o ring. I would clean in soapy water thoroughly, then blow out with compressed air. If any thread material makes it to the injectors, they will clog.and have to be removed for "Profesional" injector cleaning. I would not start the engine right after I had removed the plug and discovered it was cross threaded untill I do everything I listed above. Good Luck

Thanks for the advice. However, It isn't cross threaded. The head rounded out.

OK, I would use a small dremmel tool with a cut off wheel/disk. I would then cut a slit about 1/8" down/deep, . Then I would use a wide flat tip apex and put a 12 point boxed end wrench on the apex and remove. Remember, as you are looking down on plug, left (CCW) turn to loosen. Good Luck

Normally I would agree with this type of approach. However, the plug is recessed below the fuel rail. Making it near impossible to get any dremel bit in it. Also, the wall of the plug is paper thin and very soft. Having only ~1\4" OD on the entire plug doesn't give a guy a lot of meat to work with.
I will try one or 2 redneck approaches but realistically, I'll probably have to drill and tap. Which I am NOT looking forward to. Lol

Then use a diamond tipped bit to cut the slit from above.
Use Dremel tool BIT Diamond tip would be nice.
- I would cut slit from side to side and 1/4" down. Then use a Wide straight apex and tap apex with hammer seating it good into the allen head. before using 12 point socket wrench

I understand what you're driving at. And, again, I would normally take this approach.Then use a diamond tipped bit to cut the slit from above.

However, it isn't going to work in this particular situation.
The green portion of the plug I highlighted on the Pic doesn't exist anymore. When the allen head socket of the plug rounded, the entire wall tore off and caved. I can't overemphasize how soft this plug is.
The wall thickness that remains is basically paper thin, as I described earlier.
Plus, since the plug is recessed, the odds of the dremel biting into the exposed threads of the fuel rail itself is very high. Almost guaranteed. Meaning, I may as well drill and tap it at that point.
It's just a No Bueno situation.
Normally inwould slit it and then use something like the attached.
