I get back into the truck this morning when leaving the store, and the smell of diesel is pretty strong. And after a quick inspection with the engine running, I'm almost certain it's coming from the fuel heater. So what do I do next? Why hop on youtube of course. And there is what appears to me to be an ingenious fix using an expansion plug. First question then is should I do it? We're already down to 20F at night and it will get a lot colder. Do I need that heater or will using something like Archoil's winter diesel treatment suffice? If I go that route, and I get started disconnecting lines, are there any springs, balls, or other tiny parts that will come flying out of the items indicated below? And what should I do with the heater connector? I'm thinking i may want to leave it intact in case I change my mind and want to use it again. what would be the best way to stow it out of the way?
