Brake leak at rear hardline/T-fitting

Have a '96 w/ 120k miles 8.25 axle

It appears that there is a leak at the driver's rear hardline where it enters the T fitting at the center of the axle.

Does the T fitting ever go bad, or do I just need a new hardline?

Do I need a new hardline, or can it just be cut and reflared?

Should I replace the passenger side line while I'm there?

Where would I pick these up - online searches of the parts stores didn't find any T fittings, and only generic brake line.

Thanks

have you replaced the rear flex line before? maybe it needs tightening

Haven't replaced the flex line before, although I did bend it around some while doing the ZJ disc swap, though that was a year ago.

Don't have my tools with me but dug up a crescent wrench and was unable to tighten using that.

Will stop by advance on the way home and see if they have a more thorough inventory description at the store than online.
