i think it is a case of using the wrong material for the tank. my 88 bus
gets about 35,000-40,000 miles per tank. and i don't believe there is any
way to 'repair' the tank. :(  i suppose you could always replace the tank
with something of your own design and manufacturer, but for my cost of $40,
it's just not worth the trouble to me ... especially since the tanks seem
to last about 2 - 2.5 years.  and, yes, it seems to be a really common
problem: the dealer in atlanta keeps several of these in stock. (unlike the
ball joints, which they do NOT keep in stock).
