I did my searches in this forum for Fuel Presure and it didn't answer my question.
What is PCM/Fuel Pressure Regulator? This is listed in ALLDATA "03-017 MAY 03 Campaign - PCM/Fuel Pressure Regulator Replacement "
Google searches says it "A fuel pressure regulator is a small device with a diaphragm inside that maintains a constant pressure (or tries to) regardless of the rate of flow. Basically you can put any fuel pressure in, and get a constant "set" pressure out - however much the input pressure might vary. "
and it "simply returns the excess fuel at low pressure back to the tank via a second fuel pipe. "
So with that recall, will it improve MPG?
