The headspace of a gasoline tank is too rich to explode, and that of a diesel tank is too lean. That's why you NEVER MIX FUEL TYPES!

I torch soldered an emergency repair on a gasoline car tank - empty, but not flushed, and didn't even see a puff from it.

(and yes, I am originally from rural North Carolina. )
