AOA Brother, I have Suzuki Mehran VXR euro2 (2014), and facing the same problem for two years now. By seeing your pipes configuration I checked miine too. And found out it's not same. As this message of yours is an year old so I can assume that now you know that this setting actually works or not. Can you please tell me if your petrol smell problem is solved by this setting. Moreover, my fuel tank lid is okay.
