Before removal, clean the fuel rail assemblies with a spray type engine cleaner, GM X-30A or equivalent, if necessary. Follow the package instructions. DO NOT soak fuel rails in liquid cleaning solvent.
NOTE:
Remove the fuel rail assembly carefully in order to prevent damage to the injector electrical connector terminals and the injector spray tips.
