I apologize for no pic, and since I don't know what it is I can't do a search. On the drivers side of my 85 300d turbo there is something that looks similiar to a canister with a valve stem on top. It has a hose or tube about the size of the fuel line coming off the top but is looped back into itself at the bottom, so basically it appears to serve no purpose since its not hooked up to anything. Can someone please tell me what it is and is supposed to do. Thanks!
