If this is a rectangular Marshall Brass regulator like the ones originally
installed on the tank I expect it's a thousand years old and is leaking at
a corner of the diaphragm.  They abandoned the rectangular shape for a
round one during the nineties I think.  The round ones are a bit longer,
you have to massage the tubes running inside.  I forget the Marshall number
of the replacement but list archives will have it.
