There was a great article on this a few months back in either VW Trends or
Hot VW's.

When the tank is off the car, you put a chain, stones, bolts, nothing too
major in the empty tank and shake it around to break up the old rust,
varnish, etc.

Next, you take a metal prep cleaner that more or less cleans the surface of
any rust, or residues.

Next you pour in this stuff that is polymer based, and slosh it around in
the tank.

That is a quickie idea of the process, but it is a PITA.  Very time
consuming.  that is why I suggest finding a radiator shop that does it for a
fair price.  May be cheaper in the long run if you can do without the van
for a week or so.

I just bought a new tank, and sealed it with Eastwood's gas tank sealer, and
should be great for years to come.
