Voltage regulator? Inside the alternator. Fuel pressure regulator? Inside the throttle body.
its right on your throttle body behind your injectors on the same assembly. if you want to change it, take out your injectors but replace the whole bracket with the regulator on it. there is a spring in that regulator that will fly out if you take it apart, plus there is a good chance it will leak after you get it back together
