From the sound of it and as other pointed out, it seems you didn't get things tight enough on the first try. That's one of the things w/ AN fittings, there's no torque spec, you just have to know by feel or test to know the seal is happening and will maintain itself. We've shipped a lot of kits and people usually solve this problem with the leak test recommended in the instructions. Also, were you using the supplied O rings as a secondary seal?  As far as a 'secret' forum, the 300 Degree HPFR suport forum is open to anyone who registers their kit by furnishing the information requested on the coverpage of the instructions.
