The required items for removal include the regulator O-ring small together with the regulator filter screen and both the regulator O-ring large as well as the regulator O-ring back up. Protect the fuel pressure regulator housing by applying a cover to stop the entry of contaminants. Before installation of a new fuel pressure regulator a mechanic must utilize clean engine oil to lightly lubricate new O-rings on the fuel pressure regulator. Begin by mounting the regulator back up O-ring followed by the regulator O-ring large and regulator filter screen and the regulator O-ring small. The fuel pressure regulator must be inserted into its housing while the snap ring should be used to secure it.
