The first step to replace the Fuel Pressure Regulator requires removal of the upper
Intake Manifold before the retaining clip of the Fuel Pressure Regulator can be extracted. Using a shop towel to minimize fuel spillage you should twist and pull the Fuel Pressure Regulator from its housing. Constructive disposal of the Fuel Pressure Regulator o-ring seal and the regulator filter and then the regulator o-ring along with the regulator back up ring should take place. Protect the Fuel Pressure Regulator housing with a covering material to avoid contamination. The filter screen in the Fuel Pressure Regulator should be checked for contaminants after which a replacement may be needed for the regulator if required. The new back up ring and regulator seal o-ring should receive engine oil lubrication before getting assembled onto the Fuel Pressure Regulator with the new regulator and regulator seal o-ring. Fitting the Fuel Pressure Regulator requires you to point the vacuum tube downwards before using the retainer clip to secure it while reinstalling the upper manifold. After reconnecting the negative
Battery Cable you should tighten the fuel fill cap. End the procedure by testing for fuel leaks through a diagnostic process of turning ignition on for 2 seconds then off for 10 seconds before turning it on again. Check that no leaks occur during this test.
