Per the 2008 GCR:
9.3.26. FUEL CELL SPECIFICATIONS
2. Container
b. Sports Racing Category and Formula Cars
The fuel bladder shall be completely surrounded by a container (which may also be a part of the structure or bodywork of the car) to ensure rigid and secure mounting of the bladder and provide additional protection. A minimum of .036 inch steel, .059 inch aluminum, or an approved equivalent is required for all vehicles.

I grabbed a micrometer out of the toolbox last night and measured the very thin stock aluminum cover on my RF92 FF. As I suspected, it was about 0.032” or so thick. It seemed to be soft (5052H32?) because I could easily bend it with my fingers. Also, the bulkhead was only about 0.045” thick. How could the car pass the homologation process is the container / bulkhead are both out of spec.? My old S2 cell's container (the tub) was in the same boat - 0.050” including the floor pan it was sitting on (much thinner in reality as it was well worn.)
Did Van Diemen somehow get around the rules or am I missing something.
