fuel tank heat shields

First off, do they all have that foam insulation material between the shields and the tank? Mine does, but looking at pictures of others that doesn't appear to be a universal truth.
Anyway, it seems that the insulating foam material between the fuel tank heat shields and the tank itself also serves as an adhesive of sorts. When I popped the shields off, I broke that adhesive bond, obviously. How do I get it back? Add glue? More foam? Also, if I were to get new heat shields, do they come with foam preattached? Or is it a kind of foam I can buy in the store and just spray in there?

Here's a diagram of the heat shields. Each side is made of the 3 parts.
Second diagram is a view of the fuel system and they show only the lower part on one side for reference.

Also bear in mind, in a rear impact you might have tank to heatshield to exhaust pipe direct contact. The shields would act like a heat sink cooling the pipe when it's pushing on the tank.
