The interpretation of the rules to allow non-SFI or FIA fuel cells in IT has been prevalent for years. There are quite a few IT cars using unrated circle track cells. To my knowledge this hasn't been a safety issue. In my own case I would much prefer a circle track style cell to the poorly protected stock fuel tank. Even though lacking FIA certification, these cells have a proven safety history in the rough and tumble stock car world.

In my opinion, a rule "clarification" that would prohibit the common practice of using circle track type cells would be another example of the SCCA fixing a problem that doesn't exist.
