No baffle, tank is empty other than filler pipe that inserts a fair way. Otherwise just a fuel pickup on a sock and the float which is like a birdcage perch on a rod that moves up or down with fuel level. You probably know that already. I can't think of anything else, I've had new and used ones out and looked around in them when flushing. Is the tank out now with sender removed, can you see what's loose? I'm also imagining a plate of sorts that separates the filler pipe from direct blast on the sender nearby, but I can't recall if that actually exists or not! Otherwise I have a brand new tank in box i could dig out and see what I can see. I'm trying to think of any plate guard on the sender, have new and used here also.
