fuel pressure regulator after install

[forcedfedgsx]

after installing an adjustable fuel pressure regulator i got some issues. it was a cheap unit and i cant adjust pressure below 65 or so. If i take off the vacuum it doesnt change the reading. i have a lot of speculation on whether it works because it seemed used when i got it. Is there anything else that could affect my pressure besides the fpr.

what unit is it? I know the B&M won't let you lower base pressure ... but 65 is still way too high.

its a obx cheap ass fpr. it is supposed to be adjustable both ways but it doesnt go below 65 it goes up to like 100 or higher but obviously i didnt want it that high so i lowered it. i have checked out the aeromotive at jegs i might pick it up as long as there is nothing else that could be doing this besides a messed up regulator

sounds like something's wrong or its a piece of crap, i can see a definite change in mine when i disconnect the vacuum line at idle (it will go up actually) but mine's an sx universal.
