HOL-12-1008 Holley In-line Fuel Pulse Damper

HOL-12-1008 HOLLEY IN-LINE FUEL PULSE DAMPER

FUEL PULSE DAMPER, 6AN, EXTENDED RANGE 40-100 PSI

Features

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

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.
