I started to install the new grommet form Quantum and they sent me one mark for a 1963 to 1966 A body
It does not look like it will work, the filler hole and O.D is smaller than the one I installed originally two years ago that is now leaking and it is smaller than any of the old ones I bought from Year One 15 yrs ago
I ended up reusing the original one that I bought with the new tank two years ago, evidently I had install the steel filler pipe to far into the new grommet on
the initial installation which allowed a gap to occur between the pipe and the grommet
I could see the open space and assumed that the grommet had stretched allowing the gap
I filled it with gasoline two days ago and no leaks so far
I will buy my new grommets from the source provided to me on here from this post from now on
Thanks to all
