Usually they go from the bottom almost to the top, to within a couple
of inches or so. The bottom has the corners cut out to allow the fuel
to flow back and forth. The trick is figuring out where they are.
Hopefully you can see some weld marks or something to tell you where
they're at.

Take a look at

I cut 8" square access ports to be sealed with 12" sheets of Neoprene,
formagasket, aluminum sheets, and 8x32 screws. The baffels are floor to
cieling, and corners cut at bottom, with 2" holes in the 200 gal tanks.
No 2" holes in the 100 gal tanks. 3 baffels in the 200 gal, and 2 in
the 100 gal. As Keith says look for weldmarks, or take a clothsehanger,
and probe around. I bet you end up cleaning out the tank, so make the
goles big enough to do the dirty deed.
