Exactly, thanks Bob.
For you fellows contemplating mounting a battery or fuel cell in the back, that area must be segregated from the driver by an aluminum or steel sheet metal firewall. I used to explain to the racers that you should seal up the area so that if a person were able to stand the car on its nose and fill the rear area with liquid, none of it could leak through and get to the driver. If you can visualize the car in an "incident" and standing up against the wall, that's exactly the scenario I'm talking about. Visualize the car on fire and gasoline leaking through the firewall and down the driver's neck.
Of course you should try to make the area liquid-proof as much as possible with the metal you're using, but common sense tells you that you will have to use some other material in the small cracks and around the cage tubes that go to the rear. You can seal the area up pretty well with a good fuel-resistant sealing compound such as Permatex #2...
When you think you have the firewall all sealed up, get inside the car at night and have your buddy shine a strong flashlight from the trunk side of the firewall. You will easily be able to see any area where liquid could get through.
This is not about beating the rules to death, it's about saving your life.
