Huge difference in how a 55 to 65 acts, never mind if the calibration is for
the wrong one of the two.  If you have orther than the ones mentioned ie
green whites, you'll never be happy.

  But, even if this is so it will lean cough on sudden

Dead heading pump raises pressure, and lowers volume, doesn't
mean much.   Now if you put a guage on and the pressure doesn't drop and it
does that, then you know they are too small or calibration is off.
