Sup guys.
AGAIN guys... I NEED HELP!!! My fuel pressure WON"T GO DOWN STILL.
I finished all intercooler piping... all I need is the stupid fuel pressure.
(just to make sure, I disabled FPR, walbro 255HP, stock injectors)

OK..this is what I observed from experiment... Tell me what you think!
1) turning the top screw in or out (from all out to most in, the fuel pressure only changes 1 PSI the Most (if I see it right it goes from 55PSI to like 55.5 or 56PSI) so screw or unscrew it don't do anything except 1PSI the most.
2) when I opened the top lid of the SFMU and and just leave it open, then start the car, it's at 60PSI, which when I unhook the vaccum hose, it will go to 60PSI so basically even if I take over EVERYTHING, no disk, no spring no top lid... it still stay the same basically.
3) I unhooked the return fuel line and run it to a bucket, and the fuel pressure still 55PSI so it must not be the bad return line.
4) I finally take off EVERYTHING, and let the SFMU holding by my friend, and all the fuel line is straight down to the fuel rail and etc, and it still stay at 55PSI

NOW guys... what you guys think?? anything else other then that Bill (motofool) gave me a bad SFMU? I bought it brand new from him for $295 and now I put it on, and this is my problem.

Plesae tell me guys.
And BILL (motofool) can you give me some of your opinion also?
I will later just ask someone (hopefully I find one) their SFMU and put it in, if it works, then Bill, I want an exchange of another SFMU.
Thanks guys.
