I think everything you need to know about fuel tank and fuel system
installation is in Title 33 of the CFR:
http://www.access.gpo.gov/nara/cfr/w...cfr183_99.html

You may also want to spend some time plowing through Title 46...which
won't be easy. And then there are the CG regs...their site is almost
impossible to find anything on!
