Mine does that even after changing the lines. I figured the dorman quick connect for the upper lines (they connect around the middle of the radiator) does not connect very well. It doesn't really drip much, just accumulates over time until it runs to the bottom.
It could be that.

Do that, except make it easy on yourself. Forget the compression fittings and hose barbs. All you need is ordinary hose clamps. There just isn't that much pressure in those lines.

Agreed ^. IIRC, it's 3/8 fuel line that fits. I just did two 8" sections where both in and out somehow got mashed near my spring. Doing it all in flex line would take a bit of care routing all that. Gotta be good, or the Jeep won't go! (without fluid). I used two small clamps on each, mounted 180* apart to be double sure. (8 clamps for both splices)

My local Pep Boys had rubber hose that is specifically marked for transmission lines.
Yeah, two clamps isn't a bad idea.
