Previous owner had this line disconnected that goes to this elbow. I haven't had issues but noticed gas on my first injector and that I had a leaking o ring. Now I instead think this line is dripping fuel. Is this line important / should it be connected to the elbow?
That is the vacuum line to the fuel pressure regulator. If gas is coming out of the regulator, you need to replace it.
Thanks JKP! I opened up the fuel pressure regulator and changed the o ring out. No more leak! Did this a long time ago, but thought I would just add this reply to wrap up the issue in case anybody else runs into this.
