    It's not clear what this means. Rust is pretty stable once it forms. I mean, it can't get rustier.

    Phosphoric acid changes iron oxide into ferric phosphate ( I think ? ), which allegedly acts as a barrier, but obviously it needs to penetrate right into the rust.

    I'm sure the Phosphate worked well on a Test Bench environment.
    The same stuff, in a Vibrating Fuel tank cannot bond well enough to keep Oxygen away from the metal. Cracks will show up and the Rust will continue.

    B&S wanted us to buy new tanks. Made out of the same stuff the originals were made of.
    How thoughtful of them!
