Transmission flare fitting at radiator

[new2yukon]

So...it has begun oozing tranny fluid out my problem flare fitting. I could:

1. Snug it more...1/8 turn or so? if it snaps then it snaps..
2. Trash it. Be done w/ it and buy diff model...say ACdelco 21650 that apparently has fittings installed.
3. Try to warranty it out w/ rockauto. But if it can be used successfully I would like to save that hassle...thus my option #1.
4. Try Henkel hydraulic metal sealer....but I want confidence in this joint and feel that I would always wonder if its going to be ok...

Thoughts?

Soo.....I snugged it some more. Prob 1/6th of 1/6th rotation...hehe. Maybe 10degrees? Ever so little but it is TIGHT.

Drove it again. Pushed rpm to 3500-4000 a few times. Right now looks good. If it leaks again I am trashing it I think. And go acdelco.
