You don't think an aftermarket company couldn't reproduce a fuel tank for
less the $500?  It's a fuel tank.  These are sold all over the world, not
just the tiny USA market.  That's why they are cheap!  There are some items
I would not buy other than VW, Bosch, Manne, etc.,  but if you want to pay
$500  for a fuel tank, go ahead.  Some re-pros are better than
stock--they've seen where they have failed and are designed better.  20
years of road-testing shows alot.  Personally, I would take the original
tank out, clean it, and seal it with a restoration coating that people have
used for years where a new tank is not available.  If the tank is severely
rusted and/or dented, I'd go with the $150 tank and coat it for added
protection.
