My 69 Dart gas tank was replaced sometime in the past. Before I bought it 16 years ago. Well here about 3 months ago I had to replace the sender/ pickup in it. While out I looked in the hole and the inside of the tank looks terrible. So I knew replacing it was in the near future. Today I filled the tank past the point of the grommet/filler neck and now I have a leak at the rubber grommet. So I figured now is the time to replace the tank and grommet. My question is who makes the tank and grommet to use. Who sells the best setup.
