So I ended up throwing away the vacuum pump and the valve, and keeping
the T-piece and the vacuum instrument.  I added a suitable long piece of
tube, sucking at the end with my mouth and closing it with the tip of my
tongue. Much easier to set an accurate vacuum. Any leaks would be
indicated by the vacuum not remaining constant.

Thanks very much, Egil.

Just one more question.......

Was this done with the diaphragm spings fitted or removed?
