Brake Gurus I need help!!!!!!

[nats68]

OK Gurus I've got a problem that maybe you can help me solve.
I've got a 1968 Camaro with Wilwood forged dynalite brakes. All new brake lines from Right Stuff.
I can't get fluid to the rear brakes.
I disconnected the flex line over the rear end and attached a pressure bleeder on the end of the hard line. I was able to suck fluid from the master cylinder. I then went to the brake cylinder and pushed fluid through the flex line, when it was disconnected.
When I connect the hose to hard line it won't let fluid pass that fitting. Both the hose and hardline are from Right Stuff and appear to be correct, as far as the flare and inverted flare. The flex line is a braided stainless steel one. I also tried a standard rubber line and it did the same thing. I figured the flared end was bad so I cut the line and flared it again. It did the same thing.
I'm lost as to what the problem could be.
Thanks for any help you can give.
