Fuel tank foam

Is there anyone out there using fuel tanks filled with open cell foam?
I've heard that explosions are tamed as well as fuel slosh. I've also
heard that the foam must be replaced periodically. How often is the
replacement necessary? I'm using 100LL Av gas.


Perhaps a few metal baffels would be a better choice.

I have a couple of baffles already, but having 28 gal 100LL just behind my
head makes my nerves twitch just a bit. Having the foam is supposed to make
explosive conflagration less likely in case of a prang.

Thanks

I wonder how the safety of the foam would compare to a bladder? It would
certainly complicate the slosh issue, but might provide greater safety in
case of an incident.

Try searching for explosafe foam but do you think that a crash sever
enough to cause your fuel tank to explode would be survivable anyways.
Also fuel from a cracked tank can still catch fire with or without the
foan.
