My Dorf pickup has had this happen a few times.  The
replacement Cat back exhaust systems suck.  When an
exhaust leak allows pressurized exhaust to blast the
back tank for a while it really heats up the tank.  An
hour or so at 85 on the highway and when you open the
filler and it will blow your hat off.
