Q: How do you remove and install the fuel rail and Fuel Injector on Ford Edge?
A: To remove the fuel rail, relieve the fuel system pressure, disconnect the negative battery terminal, remove necessary parts, and disconnect fuel lines and injector electrical connectors. Clean around each injector and remove the fuel rail and injectors. For installation, lubricate injector O-rings with engine oil, clean injector bores, install injectors to the rail with new clips, and press firmly when installing the fuel rail to the engine. Secure the fuel rail assembly and check for leaks. To replace fuel injector seals, discard the upper O-rings. Install Teflon lower seals on the injectors, use a socket to shrink the seal, install a new support ring, lubricate the upper O-ring before installing it on the injector.
