Look just inside the filler neck, on the right there is a little black tab, hole it down with the nozzle which your filling up and you will be able to get more fuel in the tank

fill your tank til it clicks then lift out the nozzle and like dan said there is a little nipple inside the neck press this and the fuel will drop then keep filling the tank until you can't get no more in i.e fill to the neck. best I've done is 570 miles no cruise control, standard car.
