AEM AN6 ORB 40-70 PSI Fuel Pulse Damper, Part Number 25-4002

6AN ORB 40-70 PSI FUEL PULSE DAMPER They work in tandem with your AEM fuel pressure regulator to smooth out the pressure pulsations caused by the injectors opening and closing as well as the fuel pump operation under load.

• Engineered to stabilize pressure pulsations caused by the injectors opening, ideal for applications with large fuel injectors and high volume fuel pumps
• 1/8" NPT port on body of damper/regulators and in-line dampers for easy installation of mechanical pressure gauge or pressure transducer
• 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

The AEM AN6 ORB 40-70 PSI Fuel Pulse Damper is designed to work with an AEM fuel pressure regulator to reduce pressure pulsations created by fuel injectors opening and closing and by fuel pump operation under load. Stabilizing these fluctuations helps promote more consistent fuel pressure in demanding performance fuel systems, particularly applications using large fuel injectors and high-volume fuel pumps.

This AEM fuel pulse damper features full anodized billet aluminum construction, stainless steel springs, and a fluorosilicone diaphragm for compatibility with a wide range of fuels. The damper includes a 1/8-inch NPT port in the body, allowing straightforward installation of a mechanical fuel pressure gauge or pressure transducer. Included fittings support installation with the damper or regulator and direct-mount applications.
