From 1982 to 1988 (While working on the farm) I've fueled with the engine running:
1972 Gran Torino (My car at the time 1986-1988)
1974 Chevy Pick-up truck (Work truck)
1981 Chevy Silverado
1985 Pontiac Fiero (Engine is in the backm near the fuel point for chrisake!)
1980 Chevy Conversion Van, with drunk football fans packed inside.
and more, and this was from an above ground tank of gas, next to a
above ground tank of diesel, in the winter time when static electricity
is high.
Vehicles are MADE to be fueled when running.
Now, don't confuse OTHER fueling mishaps with a 'running car' ones
that are static electricity related: (I know you can post links to 1000's
of 'running car' fuel accidents, and you'd be right, but I bet there are
more factors like a leak, broken part, etc that are in play) but a simple
car running is not grounds for a spark.
He forgot to ground / earth the truck BEFORE
opening, and spark from HIM caused the explosion:

Again, not grounded:

BEST ONE: Notice the shirt, it's sticking to her like glue,
static electricity is MORE dangerous than a sealed engine!

Anyhow I think you got the point and well
turn the car off is NOT WRONG, just very
safe, safe is good.
