adjustable fuel pressure regulator, dumb question

[Cleaner13]

ok I have an adjustable fuel pressure regulator and its not installed at the time, however how does it actually get adjusted? Im assuming its that circular thing on the side of the regulator but that feels like its not doing anything?

thanks guys and sorry for the dumb questions

at least they're easy

Don't sweat the small stuff! If the regulator has an allen screw on top, turning it clockwise raises press. If the regulator has just a vacuum line on the top the screw is inside the vacuum line (small allen screw) clockwise raises pressure.

ok I just took another look at it and it doesnt seem to have a spot for the allen key
it does have a vacuum hook up on top and on the bottom looks like it screws in
on the side of it it has a small hollow cylinder sticking out with a rubber ring around it

? what do I do

haha I feel so stupid

The port on the side goes into the fuel rail, DON'T F%$# with it!!!! Are you sure it's adjustable? The allen screw is probably inside the vaccum line (it's really small)
