hope it helps other members out.
There is an index in the video text
I was planning to do a load test but had an airlock in the temporary fuel line, and the Lister HA4 engine stalled.
I was doing too many things at the same time and forgot to check that the fuel was flowing properly during a 5 kW load test.
An air lock got in the fuel pump and I had to purge/bleed the fuel filter and the fuel pump.
As I had not done this before, had to resort to the internet, and I did not want to crack the high pressure fuel lines to the injectors as that is not needed IMO, and often more problems are created with leaks on the HP side of the pump. As long there is fuel above the eye of the fuel pump, the pump will disperse the air out of the HP lines.
