I have a 77 el Camino classic. Why can I only pump a gallon of gas into it before it starts overflowing?
I'm having trouble filling the gas tank. It
takes 1gal and then fills up the neck. Then

almost empty. Thinking its like an evap

The gas tank vent is plugged or kinked. If it has a evap can then it is likely plugged up.
