TBH, I'm assuming the new pump is creating pressure & the issue is something else, what's the chances of a new pump not working, giving the same symptoms of no pressure as previous, hence me looking at the distribution block/relief valve.
I suppose I should confirm pressure at the pump, as my previous test, direct from the pump to the tank.
My procedure was run the engine with the valve open, then close it gradually to reach pressure.
