How to Address Issues with the Fuel Pressure Regulator on Chevrolet S10?

A technician should start Fuel Pressure Regulator repairs and servicing by uninstalling the upper intake manifold assembly. The first step is to remove the Fuel Pressure Regulator retainer clip. After that, pull and twist the Fuel Pressure Regulator while using a shop towel to absorb fuel that leaks out from the housing. One needs to remove both the regulator seal lower o-ring and the regulator assembly filter plus the regulator seal upper o-ring and regulator seal back up ring from the Fuel Pressure Regulator setup. Protect the Fuel Pressure Regulator housing from contamination by using a cover and discard the applied o-rings. It is vital to replace the Fuel Pressure Regulator only after inspecting and potentially changing the filter screen for any evidence of contamination. Place clean engine oil on the o-rings before inserting the regulator seal back up ring followed by the regulator seal upper o-ring and regulator assembly filter and finally the regulator seal lower o-ring. Install the Fuel Pressure Regulator by placing its vacuum tube facing down inside the regulator retainer clip and then add the Fuel Pressure Regulator retainer clip followed by the upper manifold assembly. Connect the negative Battery Cable while tightening the fuel filler cap. End the check by turning the ignition on twice during a 2-second period followed by a 10-second off interval before turning on again to verify fuel leak presence.
