Gas Tank/sump - will it pass tech?

I've not seen many fuel cells in doorslammers that have a bladder in them. Lots of bladders in roundy round cars!

Most aluminum/plastic cells either have foam in them or nothing at all. No bladders anywhere.

Foam or bladders, either way the fuel spillage is controlled. The OP asked for an opinion, I gave mine, as did others. Just because somethig is technically legal doesn't mean it SHOULD be run and even the OP was starting to have some doubts...........
