OK, thanks for all the replies on my tank not filling.  Today, with the
bleeder valve all the way open, it took 1/2 gallon, but took *forever* to do
so.  (i.e. about 10 minutes).  You could barely see the dial turning.
Liquid propane did eventually come out the bleeder.

Could I have something clogged?  Is this speed normal?  Could it be so slow
since it was almost full?

tx,
bmc  :)
