Possible clogged charcoal canister

where were you smelling the fuel though? engine bay or back of vehicle/exhaust?

In a 10ft radius from the truck.

yes, same, but when I get closer, I'm not getting the smell from the front, it's definitely from the back and smells like it's running rich.

I also have the ever so slightest little variation in my rpm at idle. Tiny, but there.. idle isn't 100% smooth, it's like 95% smooth. I'd almost bet there's either a slightly dribbly injector or the spray patterns on most of them aren't great and this is causing a bit of unburnt fuel to come out the back.
