Only tanks after the mid 80's (84 maybe?) have the auto cutoff, fortunately
our government interfering with natural selection once again.  Idiots should
and are entitled to die, we didn't need the addition of a commonly failing
and expensive autoshutoff fill valve when anyone with a modest IQ should
have grasped the concept of opening the 80 percent tap filling till you saw
LP then stoping.  I wonder frankly about the bus and early van tanks.  I'm
more than a bit annoyed about all the regular cylinders I have.
