• Q: How to replace the fuel rail assembly on 2009 Chevrolet Equinox?

  A: The first step to replace the Fuel Rail assembly requires pressure relief from the fuel system. Start by detaching the engine fuel feed pipe from the Fuel Rail and then going ahead to extract the upper Intake Manifold. The maintenance process begins by disconnecting three electrical connectors from the main Fuel Injector harness and Coolant Temperature Sensor and Camshaft Position Sensor all as prerequisites to disconnecting the Fuel Injector connections. The Fuel Rail assembly could be removed after dismounting the Fuel Rail retaining bolts. Extract the injector o-ring seal from the sprayer tip of each component. You should take out the fuel injectors from the Fuel Rail only if needed. Use gm p/n 12345616 (Canadian P/N 993182) for lubrication on Fuel Injector o-rings before installing the Fuel Injector nozzles into lower Intake Manifold injector bores. Use a hammer to press on the Fuel Rail until all fuel injectors settle into their correct positions before installing the Fuel Rail attaching bolts which must be tightened to 10 nm (89 lb in). Install the injector electrical connectors to the Fuel Rail before applying lubricating substance gm p/n 12377900 (Canadian P/N 10953529) to the connector points. Reconnect the electrical connectors between injector and rail. The installer should reattach the main Fuel Injector electrical harness connector after connecting the Coolant Temperature Sensor and Camshaft Position Sensor electrical connectors. The upper Intake Manifold requires installation after you connect the feed pipe to the Fuel Rail. Complete the operation by reconnecting the negative Battery Cable while inspecting for fuel leaks through three steps of turning ignition on for 2 seconds followed by 10 seconds off and then on again for leak detection.
