I have had continuing leakage problems. Mostly with the AN 90 degree fitting coming out of the bottom of the master cylinder. First used teflon tape, then teflon thread sealer (at $15 per tube!). Then used teflon tape and tread sealer, then pro-seal. Takes 3 or 4 days to develop, but still leaks. I am running out of ideas. Maybe tite-seal?
