2007 Chevrolet HHR Fuel Rail Parts Questions & Experts Answers

• Q: How to replace the Fuel Injection Fuel Rail Assembly on 2007 Chevrolet HHR?

  A: The first step is to reduce fuel system pressure that requires ch 48027 if the system includes it or no tool for systems without ch 48027. Remove the air cleaner assembly followed by disconnecting three components from their locations: the fuel feed quick connect fitting from the Fuel Rail and the evaporative emission (EVAP) purge tube from the Intake Manifold and the Fuel Injector harness electrical connector. The electrical connection for the manifold absolute pressure (MAP) sensor also needs removal. The Intake Manifold receives the removal of Fuel Injector harness electrical connector clips (4 and 5) ahead of the Fuel Rail stud removal. Dull movements are necessary during Fuel Rail assembly removal because damage can occur to the Fuel Injector electrical connector terminals and spray tips. You should pull the Fuel Rail in an upward and backward direction to remove fuel injectors from the cylinder head ports before taking out the Fuel Rail assembly including the fuel injectors. New lower o-rings must be installed for recycled fuel injectors ahead of lubricating the injector tip o-rings just before insertion into the Intake Manifold. Position the fuel injectors with their downward sides facing and then insert them into the cylinder head ports by gentle pressure. Secure the Fuel Rail bolts at 10 n.m (89 lb in). The Fuel Injector harness electrical connector and map sensor electrical connector together with clips (4 and 5) must be reattached to the Intake Manifold. Before reinstalling the air cleaner assembly you must route both the evap purge tube to the Intake Manifold alongside the fuel feed line quick connect fitting to the Fuel Rail and lastly connect the negative Battery Cable. To check for leaks turn on the ignition while the engine remains off for two seconds before turning the ignition off for ten seconds and checking again for any fuel leaks by turning the ignition back on.
