Winglet,
The only other fueling problems that I can recall seeing are:
Fuel shooting out the vents when the tanks didn't shut off.
Nozzle leak, or nozzle connection leak.
Hose rupture, caused when fueling at hight pressure (50psi) and shutoff valves closed suddenly. Hose had a bad spot that failed.
De-fueling problems: Truck over filled and fuel over flowed.
