I bought my replacement at the dealer for $600.00.

www.Busdepot.com has one:
Propane Tank, 80-91 Westy, Original Equipment Tank with Internal Fill
Valve click for picture $219.95

Here is the link, if it doesn't work search under Vanagon - Camper Parts
and Accessories.

Replacing this was a pain, but well worth the peace of mind.  Take
pictures of the layout or draw it before you start.  Be prepared to work
with propane lines.  My dad helped me with that part due to me knowing
nothing.  I had my brother spray paint the thing after I got it, the
original paint looked to be about 1 micron thick and readily rust-able.

I hear that there are places that will recondition your existing tank.
But look at the price of a new one...

I'm planning to either replace my propane tank with a new one OR to have
the old one refurbished by a company that does that...

I'd much appreciate any advice/recommendations from someones who have
been down that path before...

thanks
