Doug, I found this in my personal archives, I'm not the author and have not
done this, I thought it was worth keeping ... I'm
passing it along. This was written for motorcycle enthusiasts.

You can use a four parts water/one part Muriatic Acid (available at your
local hardware) to disperse the rust from inside the tank.
The tank must be mostly free of the varnish left by modern gasoline. I
find that a slightly rusted tank will be spotless in about an hour, up to
overnight for a badly rusted one. If there are spots where the rust has
actually perforated the tank even though the paint is still intact, this
mixture will go right thru that, so beware of that. In that case your tank
needs more work anyway. This solution isn't too bad on paint either, as
long as it's rinsed from the surface immediately.
Rinse the tank with water next to clean out the residue, then rinse with a
small amount of acetone [CAUTION: acetone will remove paint and the oils
from your epidermis, USE RUBBER GLOVES] - which will mix with the water,
carry it all out with it. Acetone evaporates very quickly leaving a
spotless surface inside the tank. The other methods, rotating rocks for
sure, and chemical boiling probably, won't leave a surface clean right down
to the pores of the metal the way this method does.
IMMEDIATELY coat the inside of the tank with the liner as it will start to
rust within minutes because it is very bare metal in there. CAUTION: the
liners will also eat paint, as they are caustic in order for form a
chemical bond with the metal surface.
Any reputable liner will probably do; I use the following because it's
always worked well for me, and is reasonably priced. The kits available at
a motorcycle shop are simply acid/acetone/liner just as I described above,
but are quite expensive and one ends up with leftovers of one or other of
the three, requiring the purchase of another kit which only . . . well, the
picture is clear.
