Some odor, but no worries with a suit (unless you wipe your hands on the suit). As diesel does not evaporate the same as gasoline, residue on the pump nozzle often gets on your hand. Many stations offer disposable gloves; I don't usually use them but last week after filling a diesel Toyota, I did have to wash my hands to get rid of the smell. Depends how much it bothers you.
