Q: How is a Fuel Injector Installed on 2008 Jeep Wrangler?
A: If the injector to be installed is a replacement of the original, make sure to replace the O-ring with a new unit. Subsequently, coat each injector O-ring with a thin layer of clean engine oil to ease its installation. Subsequently, slip the injector into the fuel rail assembly until the clip snaps securely into place. Extend the fuel rail installation next and then start the engine to confirm that no fuel leaks occur.
