However, he's right and you are not. Kerosin and diesel fuel vapours are highly explosive. This is how a Diesel engine works in the first place, and if you doubt Kerosin / Jet explosions you might want to google TWA flight 800.

Yes, a spark from a fuel pump (or a valve, cannot remember) exploded the tank and brought the aircraft down.
