Just to verify: The ports on the prop valve are not for flared lines? What brand is it?

Re:
Correct, the ports on the prop valve are not flared. It is a Classic Tube prop valve! And what are your reccomendations for adjusting it. Right now I have it set at 4 full turns out, out of a possible 8 full turns! Thanks!

If it's leaking, I don't think I'd be too worried about adjusting yet. The setting will be unique to your car, but I'd hate to even start the dialing in process with it leaking... if fluid is getting out, air may be getting in and you'd get pretty inconsistent results.
I do seem to remember reading that teflon tape/paste should never be used with brake lines.
I'd probably give Classic Tube a call and see what they recommend.. it may be that it should be flared and they just had a bad batch go out -
I'm having difficulty coming up with a reason why they wouldn't have it set up for flared lines.

The prop valve has NPT threads and takes the correct adapter to mate the brake line to. The brake line fitting doesn't go directly into the PV. Any good auto parts store should be able to hook you up. Once your leaks are history, you need to go out to a safe area of road and do some maximum effort braking, while dialing in more rear brake bias, until you just start to lock the rears; then back off to where the lockup stops.

Re
Thanks for the input guys! Yes, Classic Tube sent the correct NPT fitting to install the brake lines, but I used Teflon paste to seal the threads going into the PV and when the engine warmed up so did the paste and it ran out causing the threads to have absolutely no sealer, that is where the leak came from! Yesterday I drained the master cylinder and used Teflon tape instead of the paste to seal the threads. No leaks!!!! I let the engine warm up as warm as it will get (180
) and still seems fine! So I geuss the catch is to not use the paste anywhere there is heat involved! I shoulda known! Thanks Rick for the input on the adjustment! Now I have the leaks cured (once again ) now I can tune it in!
