First thankx to LuisV for all his help.

Just finished replacing my tank with one from a wrecked Viper. However, there was an issue with the replacement tank.

The fuel pump did not go into the newer tank as I had thought it would. The opening seemed smaller than the original one in the car.
Turns out it was smaller. Had to use a smaller seal and bevel the opening a slight bit. Then the pump went in fine.

Both tanks have the same part number .. probably different manufacturers.

Luckily, when the replacement tank arrived, it still had a seal in it. Almost threw it away ... luckily I didn't.

One other thing. I used speed nuts and lag screws to replace the fuel pump access panel and the closeout panel.
Just in case this has to be re-done in the future.

Still miffed MOPAR does not continue to make the tank or closeout panel. I still have the original tank and will gladly ship it to any company willing to make new ones again.

If you know of such an animal, let me know and I will followup.
