  Q: How to replace the fuel pressure regulator on Chevrolet Blazer?

  A: Extract the Fuel Pressure Regulator starting by removing the upper intake manifold assembly followed by the Fuel Pressure Regulator retainer clip removal. Cut off the Fuel Pressure Regulator from its housing by pulling and twisting while using a shop towel to prevent fuel spills. The next step is to delete the regulator seal lower o-ring followed by the regulator assembly filter and the regulator seal upper o-ring and the regulator seal back up ring. The housing of the Fuel Pressure Regulator should be covered to protect against contamination while all o-rings are thrown away. Prior to refitting the Fuel Pressure Regulator always check the filter screen for contamination because this could lead to regulator failure. Apply engine oil for lubrication to new o-rings before setting the regulator seal back up ring, the regulator seal upper o-ring, the regulator assembly filter, and finally the regulator seal lower o-ring. Fit the regulator with the vacuum tube facing downward before fastening it with the retainer clip. Reinstall the upper manifold assembly afterward tightening the fuel filler cap and then reconnect the negative Battery Cable. Examine for leakage by turning the ignition on for two seconds followed by a ten-second off time before turning it on again to look for fuel leakage.
