Can anyone confirm the flow rate expected with no pressure applied?
Have I got myself a duff pump?
I=92m ready to get the engine fired up when this is sorted so any help

be appreciated.

Mike,
I managed to conduct some tests on Saturday and the results are (electric
pump only):
Max pressure with no flow = 4psi
Maximum flow unrestricted (@ entrance to mechanical pump and also last
carburettor) = 90 l/h
Flow at 2.2 psi = 50.2 l/h.
It looks as if you've either a constriction/obstruction or a faulty electric
pump.
It seems worth trying to measure output from pump outlet then progressing
along the line maybe?
Hope this helps
Best Regards
