I'm not an authority on this but I suspect not.  I suspect your
troubles are from freezing from when the, um, is there another word
for idiot? vented the tank back through the fill valve.

Steven, you are extraordinarily fortunate that the filling idiot ran
into the problem, because he viciously overfilled the tank and it
could have exploded if it got hot.  The bleed valve MUST MUST MUST
MUST MUST be open while filling - it is what allows the Autostop
valve to know when the max fill level has been reached and it should
shut off, and it is what lets the attendant know when to stop filling
a manual system.  Newer tanks have a float-operated shutoff valve,
but this one does not.
