I had one similar scary event many years ago, late 80s I guess,
I was driving a hot rod old Camaro (1968) and I suddenly had a heavy smell of gas. I got out, opened the hood with it still running and realized that I was bending down over a really hot engine and a pool of boiling gasoline that was spraying out of a broken fuel line going to the carburetor ( electric fuel pump) that had filled the V of the engine. I took a few quick steps back as I got soaked with the gas and was not sure if I should run away or get back in and turn off the engine..would that make enough of a spark to set this volatile mess off?
I turned it off and quickly walked quite a few steps back and watched it until it cooled down.
That could have been bad.
