2010 fuel smell

[rep1978]

Pretty new to the cummins so not sure where to start. I get a fuel smell in the cab after coming to a stop. If the AC is on max (recirculating) I don't get it. If the window is down, I get the odor. Sitting in the drive way, I do not get the odor. Truck has 80k, just bought it from a dealer about 5k miles ago.

appreciate the help.

Please clarify if it is a raw fuel smell, or exhaust smell?

Check the pump, might have a drip where the seam is in the middle. If not check injector lines, but when they crack you usually know it. Anything wet under the hood?

Cant find anything wet under the hood. I will check the pump in the am. Thank you.
