At the risk of offending the cats, yes I think it could be possible. A diesel fuel leak under high pressure could put out a mist of fuel. It would be hard to say if an overheated turbo could set it off, but I think possible. In my early life I was a sale manager for architectural hardwood plywood products. Our mills producing the product had to have dust controls because of flash dust explosion possibility. Silos have exploded by dust ignition. It certainly seems possible that diesel fuel mist could explode. Look up fuel air or thermobaric bombs.
