So I was driving my jeep yesterday and noticed a strong gas smell. Checked my fuel lines and they were all good. Looked brand new actually so I guess the guy that had it before me wasn't completely worthless. I have been smelling it for a while and when I got under there I found a "T" connection that had one part of it unplugged. I have a diagram with a circle around the part I am talking about. The part that is unplugged is the bottom of the "T" part and I could not locate the hose that it goes to so either it is there and I didn't see it or it was for some reason removed. Does anyone know the routing that this thing is on? Does anyone know what this part does because I am thinking that this is the reason I have such crap gas mileage?
