Integral field tanks are allowed if for diesel, not gasoline. If engineered and built properly, they are just fine. I build integral tanks (water and diesel) into just about every boat we have built and they, knock wood, have had no problems. 40 knot plus boats too.

There are special resins and coatings made just for this.
