kahall82 Posted May 24, 2011 Share Posted May 24, 2011 Hi all,Just wondering if someone can help me with what I am looking at on my R688RST.What are the two components circled?? Should they be hooked up anywhere?What exactly does this air line do? It isn't hooked up on my truck and is the blue line in the following pic.I just want to make sure having these things not hooked up won't hurt my engine!!
