auto shut off dumps gas on the side

I saw a pic of the conversion for the early A. Don't know if Layson's does something similar for the later cars or not. Best I can recall, the conversion was basically some sort of washer with a smaller diameter hole welded into the fuel filler neck a little ways down from the opening. There was also some sort of removeable plug that you put in there after you filled your tank. The point of the conversion was to keep gas from sloshing down the sides of the car when cornering. Don't know if it helped or not as far as the auto stop feature of gas pumps.

You might be able to take a washer with the correct size hole to fit the nozzle & reduce the outer diameter to fit in the filler neck. Then have somebody weld it into the neck. Of course you'd have to remove the filler neck from the car first. Probably would need to drill a smaller hole in the washer to help air escape as the tank is filled. I think it might be worth a try if the problem is as bad as I remember it being on my car back in the day.
