I have gotten pretty friendly with two of the techs at Park Place Mid cities..
they did a little adjustment to the tabs inside the filler neck and if helped for a while....

But they are the ones that said the only real way to fix is a new tank.....

These are 2 great guys that have saved me hundreds, but they are used replacing parts and not necessarilly fixing or rebuilding. I have rebuilt calipers and assorted parts in the past that they would have simply changed out. Thats why I wondered if anyone had a fix....

I cant imagine what a new tank would cost...
