which efi fuel tank?

I took the route that's shown in the video. We had an old tank that we used to make the 'door' for the opening in the new tank. We used Permatex #80016 Form-a-gasket sealant along with a cork gasket that we made. - No leaks, - even with the tank turned upside down with fuel in it. We were able to retain the stock sending unit also. New stock a-body tanks are pretty inexpensive, so the worst thing involved was just the labor.
