Leak On Passenger SideUnder Cover

I Noticed A Puff A Smoke From Right Side of Engine Bay...When I Opened Up The Engine Compartment It Looked Like It Was Coming From Under The Covers Where Computer Is But Up By The Fire Wall Area Where Cover Is Silver. I Removed The 3 Covers And Found A Line Wet That Connects To Some Type Of Resevoir...Anyone Know What This Line Is Or What The Resevoir Is?
