get rid of that piece of shit ebay fuel pressure regulator

stay away from the aem regulators


random lean is a good sign the regulator is leaking and not maintaining pressure

fpr is not a brand like aem. fpr mean Fuel Pressure Regulator. Stock fpr means use the fuel pressure regulator that came stock on the engine.
