How to Remove and Install a Fuel Pressure Regulator in Subaru Forester?

Disconnect the cable from the negative battery terminal to relieve fuel system pressure. For 2000-2004 models, remove the air intake duct, disconnect the vacuum hose and fuel hose from the fuel pressure regulator, remove the regulator mounting screws and old O-ring. Install a new O-ring, lightly coated with clean engine oil, and check for leaks.
