Help, Nismo FPR acting up!

[joel & viola]

Heeeeeeeeelp! I just got a nismo fuel
pressure regulator. I hooked it up and
 it won't hold fuel pressure. The pump
runs the pressure up to 99 and then it
just falls rapidly until it reads low again
(below 11 psi) I then tried starting it
setting the fuel pressure and it wouldn't
go above 27 psi. :(
Anyone else ever experience this with
the nismo? What did you do to get it
operating correctly? Am I doing
something wrong?
On a side note for those who own one,
can you check and see if the top of yours
swivels? When I hooked the vac line up
I noticed that it turns freely. It would
only stop if I had the adjustment screw
turned all the way down. Thanks peeps.
