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.

Most times fuel tanks are removed from vehicle and pressure washed there is
no need to cut extra access holes.

Really? Well come on over and yank out my two 350 gallon tanks and
clean them up for me. I'll give you $100. Of course that covers
removing and reinstalling the engine, bulkheads, wiring, plumbing,
water heater, accumulator tank, FW pump, etc. etc.. etc. Oh yea, and
you're going to have to pump out and store the 400 gallons of diesel
that's in there now.

WOW Keith :
I did the 2 200 gallons one at a time, transferring fuel back, and
forth from tank to tank. Took a LOT of time, and fouled 2 transfer
pumps in the process. Used 4 5micron filters to clean during transfer.
Had to rip out the entire floor to do this. (easir than removing the
engines, and if i did i figgered i couldn't get them out anyway!)
engines 6ft long, tanks 8ft long. Wish I had found a $100 guy! How
old are your tanks, we might want to check it out if they have been a
diesel breeding ground for several years. Boatshot, and Tank shots at:

I'd like to know your plan with the Neoprene, Formagasket and aluminum.
You're going to layer them somehow I take it.
I know the Formagasket will stay soft in case you want to remove them.
