My Carb tanks > don't seem to have any baffle, but it may be an age difference. That "collar" is actually a cup with a bottom that is tacked to the bottom of the tank. The fuel outlet with the screen sticks up through 1 hole in the bottom of that cup, and the FI return line pokes up just a tiny bit through another hole. That second hole is the same size as the opening in the fuel return line, spaced just a bit above it, and "dimpled" upward, so fuel from the "outside" can flow under the cup and will then be "pumped" into the inside by getting caught up in the return flow. This will keep the cup full even when the rest of the tank is almost empty. I figured that it was a way to squeeze the last drop of fuel out of the gas tank before it would run out.
