Yea there is a overflow/vent on marine tanks. Your car does not have this
it just backs up out of the filler neck, tripping off the nozzle. Next
time jump in the boat and turn on the key and start filling while watching
the gauge. When it hits full, stop. Your luckily technically they could
fine you for spilling that much fuel onto the ground and I bet if the
station owner saw you do it he would have had a stroke...

Didn't mean that to sound quite so snotty...sorry, but you know what I mean.
:-) I always use the gauge in my boat and my trucks because I tend to use
the big truck diesel pumps. The high capacity nozzles don't shut off most
of the time. Anyway good luck...
