Master cylinder leaking
Guys I have a 2007 Jeep Wrangler jk 6 speed manual tranni. My master cylinder is leaking from were the metal tubing connects to the master cylinder and held in by a metal u clip type thing. I took it apart and there is a rubber ring thing inside the master cylinder that goes on top of the metal tubing. It doesn't really look warn. Don't get why it keeps leaking anyone know a fix or can help? I replaced the slave cylinder about 2 years ago. Factory master and metal tubing.

I'm not sure what I'm looking at here, but what you have shown doesn't look like the MC to me.
Manual trans however do have an additional connection to the brake system for the clutch, so maybe that's why I'm not recognizing it. I see the brake booster which is where the MC mounts, is that below the booster? It's hard to tell from that pic

That's the metal connection line that's leaking....

I feel like I stopped the leak from the clutch master I don't see any more leaking problem is I put tire back on jeep lowered the jeep off the jack and guess what got a crap load of brake fluid coming out of the bell housing. Could this be caused by the slave cylinder being bad I see that the slave is a bit wet from were it goes in and such but most off all the water fall came from the bell housing. Any ideas?

Yup slave cylinder sounds like it's bad too. At least those are pretty cheap and usually have lifetime warranties. Make sure to spray inside the bell housing with a crap ton of brake clean to get that brake fluid off the friction plate. Brake fluid is highly corrosive for your clutch.
