<< CASC ( and probably SCCA, since CASC copies a lot of their regs directly

expensive cross-linked plastic hard bodied cells. it has to be installed
in a hard container, etc. and it is probably lifed at a replacement age

This really isn't rocket science. FT-3 is the standard that any knowledgable
organization goes by. This has been the FIA standard for years for our kind
of racing. Any cell manufacturer can tell you which cells they make that meet
the FT-3 specification. If they don't know about FT-3, then don't buy it.
FIA has higher ratings, but they apply to F-1 and other pro series. Just
stick to FT-3 and you will be sure to have the right item.
All manufacturers recommend bladders be replaced on a five year cycle. It
seems that foam most foam starts to break down after 6-8 years. I believe
that storage with the foam immersed in fuel extends it's life.
