Doing some maintenance, I realized the line coming from the turbo crossover pipe to the fuel pump was disconnected. I reconnected it and drove around for a minute and did not notice anything other than my green turbo light on my tach coming back on for the first time in months which was kinda funny. I can't find a description or a thread, mainly cause I don't know what it does. I would appreciate some info. It is the line coming out of the "B" in Turbo.
