The small plastic line is a vent from a pressure damper in the fuel circuit. It shouldn't affect the way the car runs. Its there "just in case" the diaphragm in the damper ruptures. I guess they figured if the leaking fuel went into the air cleaner, it was safer than having it spray all over the engine.
