Aeromotive AFPR

[Got Boooost]

Hey guys,
Ive got a new Aeromotive fuel pressure regulator and after doing a boost leak test I found the adjustment nut on the top of the unit leaks air. is this normal? I tighten it up some more but it still leaks. will this effect the preformance of the regulator? is there something i can do to completely stop the air leak?
Thanks for the help

Either that or some sort of liquid thread sealant will work.
