It's part of the fuel rail. Just after the first injectors from the driver's side, there is the electrical connector for the fuel rail. Just under that connector there an "L" shaped hose that comes out just under the throttle bottle whatever connects into that accessory hose is what is missing. One person said it might be some sort of test port for the fuel rail. It has never had any electrical connection to it, it was just some sort of plug there before. There is a bracket there where it used to just snap into place. Now I'm at a loss as to what to do next. Should I just replace the fuel rail or what?
