To aleviate the needles pulsing though ( I suspect yours are the same ) mine have inline thumb screws that adjust and lessen the higher than needed vacuum amount thereby preventing any pulsing.

Hey Staffo,

I call those thumb screws "snubbers" and you are right, mine came with them. Work really well.

I also prefer the needle gauges and the simplicity they bring to balancing. Can't beat the price also.
