Yesterday I filled our '88 Westy propane tank for the first time this
year (it was totally empty). All went well, except after closing the
bleeder, gas continued to bleed from a small round hole in the
casting just about the bleeder output. Seeing that the attendant has
put over 10 litres in, and I seem to recall the tank only holding 9
or so, I assumed he had overfilled, and this was an overpressure
valve. I bled off more gas by opening the bleeder knob, which took a
minute or two before the stream turned from liquid and heavy white
gas, into what appeared to be just air. I then closed the knob, but
the pinhole was still letting out gas, although much slower now.

This morning the leak seems to have stopped, but a soap test still
shows a very slow leak at the pinhole.

Has anyone seen this before? What is the purpose of this pinhole? Is
the filler assembly a standard item that a gas shop can
check/repair/replace, or is it Westy specific?

ps:  I also removed the fridge, cleaned, and re-installed yesterday,
which was easier than expected. The burner was also in better shape
than I expected, so I'm not sure why it's so hard to light...
