My '90 tank baffle has broken the spot welds along the bottom of the tank, but the one on the rear is still solid. The baffle moved over and trapped the fuel sender float, holding it at the bottom of the tank.
I've heard 2 suggestions so far:
1) Try to work the baffle to break the spot weld holding it to the rear baffle.
2) Use an epoxy (like http://www.amazon.co.../…/B000ALG8RS ) to hold the baffle in place along the tank floor.
Here are a couple of pictures:
