Hello. I noticed a little fuel smell while I was cleaning my truck for the carlisle mopar nationals. The bottom of the tank was damp with fuel (trickled down the side) I noticed thst looking between the bed ad cab fro the side that the hose in the picture is wet....looks like just the hose. (I borrowed the pic from here) What is this hose for and where does it go? Noticed the truck takes a little longer to start lately also...not a lot longer but noticable.
