Im removing the saddle tanks out of my 42 fountain some years are different but these are foamed in and bolted to a front and rear bulkhead.
I have been cutting the foam with a wallboard saw and there not budging I even used a come along between the two tanks
Is there something to eat away this foam? Besides the extra room I need to fix the bulkheads. As far as the repair I plan on using polyester resin and 1.5oz cloth doing 5 or so coats wet on wet and probably beef up the area with a brace
