Before ripping through the tank, I checked the depth against the fully-lowered blade. At the rear L corner, there was ~1/4" interference. To clear the tank, I simply tilted the saw. Another option would be to position the blade at its maximum UP stroke, then mark & break it off ~3/4" below the saw's shoe.

But an air hammer with slitting chisel is safer, quieter, & quicker.
