Stick an allen key into the centre shaft to stop it spinning. Then undo the nut.
I think you should buy a set of jubilee clamps for the tiny hoses around your WGFV as they had been there for ever and need replacing.

You can only do that with the WG removed from manifold !

With a top only access you need to *CAREFULLY* lever something into the space between the diaphragm cap and the body to stop it spinning.

However, FWIW - its best to use an airline or handpump to check integrity of WG diaphragm in situ on the car without any dismantling.
