  Q: How do you replace the injectors and Fuel Rail in your Cadillac Escalade?

  A: To replace your vehicle's fuel injectors and O-rings, relieve fuel system pressure and disconnect the battery. Remove the air intake duct and, for non-6.0L models, the intake manifold and Fuel Pump/rail insulator. Disconnect the fuel lines and injector electrical connectors, and remove the fuel rails and injectors. Remove the old Teflon seals and O-rings from each injector and clean the grooves. Install new seals and lubricate the new O-rings with engine oil. Reattach the injectors to the fuel rail, reinstall the rail, and secure it with new retainers. Apply thread locking compound to the fuel rail bolts before tightening. Reconnect the fuel lines, replace the Fuel Pressure Sensor, and reassemble. For 6.0L models, remove the intake manifold cover and bracket, disconnect electrical connectors, detach the wiring harness, and disconnect the PCV hose.
