Fuel pulse dampers work with the fuel pressure regulator to further stabilize fuel pressure in an EFI system, smoothing out the rapid pressure pulsations created by injectors cycling and the fuel pump running — pulsations often too fast for an analog gauge to show but that can still disrupt fuel delivery.

It's built for an extended 40-100 PSI range.
What fuel types is it compatible with?
Gasoline, ethanol, methanol, and E85.
What thread does it use?
An 8 AN male fitting.
Does it include mounting hardware?
Yes, it includes a vacuum fitting and one foot of hose for vacuum referencing.
