Does anyone have the length of the fuel filler for a 78 Deville? I have been looking to replace my gas tank but no one is selling for the Eldog. I was just chatting with someone on fb that had said they replaced theirs with a 78 Deville some years back. I know the gas tanks are supposed to be different but I see the fuel sending units are the same.

I am going to give this a shot if I can get some measurements for the filler tube.

Thanks.
