Broken vent valve in one of the tanks is a common cause as is a duff refuel valve.
Or in our case a higher than recommended volumetric shutoff figure.:ok:

More-than-normal fuel expansion when going from a cold underground tank on a warm, sunny day -- especially when filling to max fuel!

Not all contingencies can be accounted for in engineering... :suspect:
