I got everything hooked up yesterday, poured fluid in the master (which is brand new) and had leaks running out my ears. Everything from the master, P.valve, to the bleeder valves, leaked. I did have to buy two adapters for the front out on the p.valve as the thread size was to big. I didn't use any teflon tape anywhere. Any ideas? thanks ( it takes a Mopar, to beat a Mopar! email me at moparleaner@gmail.com )

They have to be oiled which I bet they are now and then be really tight, like tighten them and loosen them then tighten them again and again until they seal up. They have to be really tight and lubed when you tighten them, did I mention they have to be tight, real tight? And no teflon tape and anywhere near flare fittings, like the inverted flares your trying to seal. Plus you better have GOOD line wrenches, no way reg wrenches are gonna work with stainless lines!

For problem connections I have put a TINY dab of rectorseal (pipe dope)at the flair to help lube the sealing surface connection and seal any small imperfections. Those flarite seals seem do the same without risk of contamination.. I would like to try them.

The AN fittings use a 37 degree flare. SAE double flare is 45 degree. You can use the stainless line and make 37 degree single flares and use the AN flare nuts and sleeves.
