Well I took out the fuel pump assembly, put it in a bowl of fuel with the swirl pot full as well and connected 12V.
No fuel came out of the nozzle, so I thought it may be the regulator packing up.
I took out the spring from the regulator and extracted the fuel regulator (housed in the top of the fuel pump). I then applied 12V again.
No fuel came out of the hole where the regulator went in.
It is definitely 100% the fuel pump
Anyhow, I'm going to retain the fuel pump assembly, the sender unit and the regulator and purchase a good quality high performance submersible fuel pump that handles greater than 3.5 bar (50.75 lbf.in2) and 120 litres/hr (211 pints/hr) (234 US pints/hr) and drop that into the swirl pot of the fuel pump assembly so that it's filter is at the bottom of the swirl pot and all I have to do is connect the output from the new pump to the input where the regulator goes and modify the electrical connection...not too close to cause a spark though, otherwise BOOM
Here's the fuel pump assembly ready for the new pump:

Here's the buggered fuel pump:

Better solution at 1/3rd the price!!!
Lessons learnt:
A running fuel pump doesn't mean it works.
The fuel pump is activated when cranked and when the engine is running, not when in key position II
Test a running fuel pump for pressure sooner than later.
