Caution: Refer to Relieving Fuel Pressure Caution in the Preface section.
Caution: Relieve the fuel system pressure before servicing fuel system components in order to reduce the risk of fire and personal injury.
After relieving the system pressure, a small amount of fuel may be released when servicing the fuel lines or connections. In order to reduce the chance of personal injury, cover the regulator and the fuel line fittings with a shop towel before disconnecting. This will catch any fuel that may leak out. Place the towel in an approved container when the disconnection is complete.Caution: Refer to Battery Disconnect Caution in the Preface section.
Notice:
• Use care when servicing the fuel system components, especially
the fuel injector electrical connectors, the fuel injector tips, and
the injector O-rings. Plug the inlet and the outlet ports of the fuel rail
in order to prevent contamination. • Do not use compressed air to clean the fuel rail assembly as this
may damage the fuel rail components. • Do not immerse the fuel rail assembly in a solvent bath in order
to prevent damage to the fuel rail assembly.
Important: If an injector becomes separated from the rail and remains in the cylinder head, replace the injector O-ring seals and the retaining clip.
Important: Different injectors are calibrated for different flow rates. When ordering new fuel injectors, be certain to order the identical part number that is inscribed on the old injector.
Notice: Refer to Fastener Notice in the Preface section.
Tighten
Tighten the fuel rail retaining bolts to 25 N·m (18 lb ft).
