New Brake Master Cylinder Leak

[Blindhuckster]

I had the same issue with a new master cylinder a couple years ago that I purchased from Dennis Carpenter. Leaked in the exact same spot. I tried multiple times with different washers without resolve. It seemed to me that the master cylinder outlet port was not drilled squarely and was drilled at an angle from looking at the washer. They were only seating on one side of the washers. Ordered a new replacement master cylinder, washers and block fitting from the early ford store and that solved the problem.
