Brake Master Cylinder Leaking

[truthtrans]

Hi everyone, I'm new to this forum so sorry if I'm posting in the wrong place. I would say I'm a novice when it comes to cars. I can change my own oil and replaced one of the motor mounts and the radiator fan for my pt but that's all the work I've ever done on my car. Right now I'm having a problem with a very slow leak (I guess it's been going on for years) in the break line going into the very bottom of the master cylinder. I wanted to try to tighten the connection there with a wrench to see if that helps the problem but was wondering which way to turn to tighten it. i.e. do you tighten to the right or left when looking down at the master cylinder from the top/under the hood? If anyone can help me with this/has any suggestions I would really appreciate it. Thanks!
