So your telling me the Regulator is located under the hood and not down at the Gas tank on this 2002 Impala with the 3.8L
Expert:  Bill replied 3 years ago.

Yes, The fuel pressure regulator is on the fuel rail and is retained by a clip. There will be fuel pressure behind it so the fuel pressure must be bled off prior to removing it or fuel may spray and could get in your eyes.
