It'll never happen.  VW never made a tank without the inverted hump.  The
reason for VW to continue with the current design is to consolidate parts
and manufacturing and is and was to keep manufacturing & inventory costs
down, relatively speaking.  I run a brand new tank in my 84 Westy with no
problems to speak of.

That inverted hump is not really a design flaw.  It's there for the hot air
tubing for the air cooled models.  VW kept it that way because of what is
indicated in the first paragraph.

At VWG/Airhead, we briefly (VERY BRIEFLY) looked into reproing various gas
tanks and for the Vanagon variety with or without the hump, the tooling was
around $100K, with a minimum first order of 1000 tanks at about $380 per.
Anyone got half a mill they wanna burn? ;-)
