As a newbie here and new owner of a '95, I've read info about not topping off too much to allow for gas expansion and to avoid overflow. But the California gas nozzles shut off way too soon when seated/sealed on the tank due to several inches of the nozzle protruding into it. How do you all do it? Hold the seal back and fill to within an inch or two of the top, or is that too much? Any info appreciated!
