My background is structural firefighting, not aircraft, so I'm no
expert on the subject. That said, I will state that the idea has been
considered, even tested; basic result is that the added weight of foam
and equipment, the danger of a falsely-triggered system,  the fact
that foam does not really work by simply pumping it into the fuel
tanks, etc., all work against your idea.
