We get this "occurance" occasionally at my store (gas station) Seems the newer model gas pumps have a sensor that stops pumping when the tank isn't full, and it happens with some vehicles, but not all. Something to do with the fumes~the rubber cover thingy blocking air flow and fumes building up, er something like that (Owner got too techy explaining it and my eyes glazed over)
Buttttt...the solution! If you pull the pump handle out slightly, more air gets ventilated in and out of the gas tank and it keeps the pump handle from clicking off. Works every time.
Thanks, Chris and Ernie!
