The AEM AN6 ORB Fuel Pulse Damper (Part Number 25-4002) is designed to enhance the stability and reliability of your vehicle’s fuel system under high-demand conditions. Engineered specifically to work in tandem with your AEM fuel pressure regulator, this damper effectively smooths out pressure pulsations caused by injector operation and fuel pump loads. This ensures consistent fuel pressure, which is critical for maintaining optimal engine performance, especially when equipped with large fuel injectors and high-volume fuel pumps. Constructed from full anodized billet aluminum with stainless steel springs and a fluorosilicone diaphragm, the damper offers durability and corrosion resistance for demanding automotive applications. Its compact design integrates seamlessly with standard fuel systems, providing a reliable solution to pressure fluctuations that can compromise engine efficiency and power.

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" NPT port on the body of the damper/regulators and in-line dampers for easy installation of a mechanical pressure gauge or pressure transducer
