You should have a gauge sitting on top of your fuel filter.

Look on your fuel rail, the FPR should be attached. Chances are it will be bling silver, red, or purple.

Pull the hose that is attached on top of it, that goes to the intake manifold. Start your car and check the fuel pressure on the gauge.

Loosen the nut on the top of the FPR using a 1/2" wrench. Then turn the gold line itself counter clockwise (I beleave, watch the gauge it will move up or down). A very small socket fits on the end of it, but I just used an adjustable wrench to move it.
