I agree. And as I recall 6 cylinder Healeys had two different oil pump
designs. Perhaps one design produces bigger pulsations.

  I disagree. In a braking system the transmission of force/pressure has
o be instant and precise so no volume of air to compress can be allowed
s that would take to much travel from the brake pedal. The brake force
n relation to the force applied to the pedal would not change, although
ou will never reach a decent force as the brake pedal cannot travel far
nough. In a pressure gauge it does not matter how much oil flows in the
ine, there is plenty of it so with or without the air it will always
ndicate the same pressure: the pressure the oil pump is delivering or
ather the opening pressure of the relief valve.
owever I can imagine that without air in the line the gauge may vibrate
epending on the design of the oil pump.
