Attached to the end of the fuel rail (pie that connects to the injectors) there should be a round metal thing with a vacuum hose attached to it. This round thing is your fuel pressure regulator. Do not disconnect the vacuum hose with the engine running if you suspect a bad regulator, as fuel may spurt of if the diaphragm leaks and this could be a fire hazard.
