Hi all, Last day when I started my Duramax in the morning some kind of fuel smell was coming from the front side. Everything was normal after driving some distance. The same issue happened when I stopped the engine. Is this something related to the engine? Can somebody tell me what it is?

Have you opened the hood, looked through the fender well or looked under the truck on a creeper to see if you see fuel dripping anywhere?

You need to change the heat range on your spark plugs, they are causing unburned fuel to escape from the transmogrifier.
