2007 Chevrolet Corvette Fuel Rail Parts Questions & Experts Answers

• Q: How to replace the fuel rail assembly on 2007 Chevrolet Corvette?

  A: A cargo truck should start by disconnecting the negative Battery Cable before beginning work to replace the Fuel Rail assembly. The first step opens up the engine sight covers along with a procedure to drain fuel system pressure. A compressed air system should clean the Fuel Injector while cleaning the Intake Manifold. Connectors should be marked to indicate the first Fuel Rail injector fitting relationship before disconnecting the fuel feed line from the Fuel Rail. Mark the Fuel Injector electrical connector position before completely disconnecting all electrical connectors. Detach the Intake Manifold bolts followed by the Fuel Rail mounting bolts before removing the Fuel Rail assembly from the Intake Manifold and extracting fuel injectors out of the rail. Install the fuel injectors into the Fuel Rail by applying a small amount of clean motor oil to their o-rings. The Fuel Rail must be installed onto the Intake Manifold while threadlock of gm p/n 12345382 (Canadian P/N 10953489) or its equivalent is applied to the Fuel Rail and Intake Manifold bolts threads. The Fuel Rail stop bracket should be properly mounted onto the engine assembly to stop fuel spray when the vehicle collides front-on. Fasten the intake bolts at 10 n.m (89 lb in) torque and proceed to secure the Fuel Rail mounting bolts using the same tightening value. Following Fuel Rail connecter reinstallations along with the fuel feed hose to Fuel Rail connections you must reattach the negative Battery Cable. A fuel leak check can be performed by turning the Ignition Switch on for 2 seconds followed by waiting for 10 seconds while off before turning it on again to check for leaks. Completion of the procedure requires installing engine sight covers while conducting transmitter programming. Procedures using the fuel pressure gage (J 34730-1A) combined with the tool set, fuel line quick connect separator (J 37088-A) serve to execute this task.
