I'd heard of doing this.  Is there another product that might be safer
than muriatic acid, like POR-15's Metal Prep?

I don't know the configuration of piping inside the tank.  If I drained it
and then added a gallon of muriatic acid or other rust remover, would that
find its way to the sump where the possibly clogged inlet screen lies?
Will a following gallon or two of gas work to remove it via gravity, or
does the fuel pump create a vacuum and it needs to be deployed to remove
the contents?  If so, would those products harm the fuel pump?

Or is this a good deal more complicated?  Anyone tried this before?
