What is the secret to filling up a 62 Nova without spilling gas all over the side? I don't use the trigger lock on the pump anymore because it never kicks out until it is too late. I now try to hold it lightly until I hear gurling and stop, but it still sneaks up on me sometimes and spills like it did today. Good reason to wash and wax but this is getting old. Am I the only one? Does anyone have a good way to prevent this?
