Sorry, I don't mean metal particles from cylinders and rings and bearings and stuff.  I should have said "particulates" in the fuel system; could be any and all kinds; maybe a little metal from the fuel pump workings or fuel tank itself but also bits of rubber, plastic, dust, etc. that entered fuel system during the original assembly process at the factory and manufacturing of the rubber and plastic fuel lines.  Probably minimal, I agree; and that's why on 86 and newer the engineers decided it was probably overkill and more harm than good.  And that the grey round metal fuel filter post-fuel pump would do the job sufficiently.

    Curious as to how "metal particles from initial engine break-in" would get into the GasTank ~
