My new Prop Valve leaking in odd spot - help!

[Orange]

To get you up to speed - I installed new system - 9" booster, master, and prop valve.
Prop valve is mounted on frame (yes it is disc/drum) and everything has worked great up to this point.

Now, my prop valve is leaking fluid like mad from the bottom. It is brand new - about 2 weeks old.



It is coming out of that little black port. What is that? Why is it leaking? How do I fix it? Now I am commissioned to no wheels - except my bicycle. HELP!

BTW - When I checked the master - the rear bowl was the only low - front was fine. The rear rubber on the cap was sucked down as well. (Due to being low). It was far from empty - probably about halfway.

Brake performance was very poor though when I was coming home to fix this.

And now I can say - after filling the master up and making sure all lines are tight and everything, it is still almost non-existent braking. And it is still leaking.

The only thing that I can tell you that is different from factory (aside from location) is that I used 3/16" line to the prop valve instead of 1/4" - but nobody ever confirmed that this would hurt.

So, whatever that little guy is affects braking severely. What really worries me is that there is no brake power, and no light on the dash (although it is hooked up).

Is that hole threaded? I have a new one like that at home, so I can't compare. If it is threaded, plug it, if not, get a new one...

Hole isn't threaded that I can tell.

If I get a new will it fix it, and why? And why did it go bad so quickly. I can't afford a $40 prop valve every two weeks.
