Overview

Holley EFI Fuel Pulse Dampers

Holley EFI fuel pulse dampers act in tandem with the fuel pressure regulator to further control the fuel pressure in an EFI system. They act to smooth out the pressure pulsations caused by the injectors opening and closing as well as the fuel pump operating. These pulsations happen so quickly that in many cases they can't be identified with an analog gauge but can cause issues with fuel delivery to the engine.

Options include:

* Direct-mount or inline mount
* Multiple inlet/outlet dimensions
* Standard or extended fuel pressure range
* Male or female threads

Features:

* Engineered to stabilize pressure pulsations caused by the injectors opening; ideal for applications with large fuel injectors and high-volume fuel pumps
* Compatible with any fuel; full anodized billet aluminum construction with stainless steel springs and fluorosilicone diaphragm
* Fittings included for damper/regulators and direct-mount dampers
* 1/8 in. NPT port on body of damper/regulators and inline dampers for easy installation of mechanical pressure gauge or pressure transducer
* Vacuum fitting and one foot of hose included with all dampers for vacuum referencing
