Does your fuel-pressure gauge fluctuate noticibly ?

Mine vibrates at about a 3Hz rate between the
middle and bottom of the green-band.
Engine runs fine...

Turning-on the electic pump reduces the amplitude of
the swing and stablizes it at around mid gauge.

Is this 'normal' ??

My 69 model does not fluctuate. Air in the line?
