PHF32 Accelerator pump No Pump...

Hi All,
I have rebuilt the PHF32s with new acc. diaphragms. And I don't see any fuel squirt. Somebody said to put your finger over the check valve at the top of the acc. pump, but I do not see any connection to atmosphere in my check valves --there is a brass plug in the center.
Questions: 1) Should you be able to check the check valve function by blowing by mouth? I can't seem to blow in or out of the internal (small) end of
the valve.
2) Does the pump sometimes need to be primed?
3) Somebody said that the jet and the jet holder at the side of the bore had to be critically aligned such that the slots in the jet aligned
with the jet holder when screwed in tight. This makes no sense.
Thanks!
