    Where does this hose go?

    Looks like a vacuum hose? Where the hell did it come from? Car seems to run fine, however I would love to put this hose back to wherever it came from.

    Looks like the hose from the fuel pressure regulator to intake manifold. Make sure there's a hose on both sides of your FPR
    Thanks,

      The intake to fuel pressure regulator is present. The intake to FPR hose is also every so slightly thicker and slightly longer. I'll keep in my to check the other side of the FPR, any other ideas?

          Note: The coolant breather tube is also present so it cant be that.

              Is it possible it could have been replaced and the old one left somewhere in the engine bay? This just really looks like the stock hose... especially because both ends are a little bit widened out from being slid onto something just the same length mine seem to be.
              Thanks,
              Matt

                  I was having a provincial saftey inspection and it did involve replacing 1 nozzle. That is where I found it atop my fender lip (where the bolts are). Perhaps the inspecting tech was planning to change a part of the tubing for the spray nozzle but didnt?

                    i would say to not worry about it.

                    do you have the breather hose on your charcoal filter?

                              The only thing it can be is the FPR hose. Since it's not, don't worry about it.
