When I bought my Jeep a month or so ago, it had a really bad/rich gas smell when running. I took it in to a mechanic and he mentioned that the fuel injection had a vacuum leak and he fixed it.
I've taken it out a couple times since and the smell was gone until I took it out on Saturday and the smell was back and again very rich. I pulled over and there was a bunch of gas leaking out of the part I have pointed out on the attached picture. (this isn't a picture of my engine, but it's an AMC 360 that looks the same). Someone mentioned that was a fuel vaporizer or something similar?
Anyone else experience a similar problem and/or know of a resolution?
