What's left?

The reason Nissan used the damper in the first place was not just because
the stock rail is restrictive and more prone to pulses, but also because the FPR is so small.

The smaller the FPR's diaphragm, the more prone it is to pulsation.
When you switch to an A/M one it's usually got a much larger diaphragm and cancels the need for a damper.

Plenty of people run A/M FPR's without dampers, at really high HP without problems.

I like my A/M FPR because not only can I run whatever size line I want, but it also highly declutters the plenum, taking away unnecessary failure points.
