Iīve followed the scheme at FC3S Pro, with some small changes.
But I have one question, there are no pulsation dampener in the scheme
and why is that? Arenīt there any need for it?

This is how Iīve done:





Thanks, Oscar

Your Aeromotive FPR acts like a pulsation damper.
I believe it even says that in their literature?

Thanks Ted! I suspected that but wasnīt sure.

An FPR is the same thing as a PD but with a bypass.
I've poked around the Aeromotive website, and there was no mention of this, but SX Engineering makes a similar FPR model, and SX does explicitly state a PD is not necessary.

Taken from "SX Performance Fuel Injection Fuel Regulators":

"The extra light weight diaphragm assembly provides excellent pulsation dampening, to dampen the pressure spikes caused by fuel pumps and cycling injectors."
