Fuel Rail & Injectors: Notes
CAUTION:
When servicing the fuel rail assembly, be careful to prevent dirt and other contaminants from entering the fuel passages. Fittings should be capped and holes plugged during servicing. Before removal, the fuel rail may be cleaned with a spray type engine cleaner, AC Delco X-30A, following package instructions. Do not soak rails in liquid cleaning solvent. Fuel injector "O" rings should always be replaced whenever the fuel rail is removed for service.
