Please remove the vacuum hose attached to the pressure regulator followed by removal of the snap ring. You should turn and twist the fuel pressure regulator while holding it with a shop towel since the towel serves to catch any fuel that spills from the fuel pressure regulator housing . The procedure continues with removal of the regulator O-ring small combination object along with the regulator filter screen and regulator O-ring large and, lastly, the regulator O-ring back up. Stopup the housing of the fuel pressure regulator before starting to avoid contamination. Installation should not include compressed air use for either testing or cleaning the fuel pressure regulator due to potential damage. The fuel pressure regulator filter screen can be cleaned with gasoline but immersing the pressure regulator into a solvent bath should be avoided. New O-rings should be added to the fuel pressure regulator before installation but they need engine oil lubrication. The installation sequence requires the regulator up O-ring followed by regulator big O-ring and then the filter screen and closing with the small O-ring. After inserting the fuel pressure regulator into the fuel pressure regulator housing users should secure it using the snap ring. Attach the vacuum hose to the fuel pressure regulator followed by installation of the fuel injector sight shield. Complete the inspection by starting the ignition for ten seconds followed by shutting it off and another start-up for leak identification.
