AEM AN6 ORB Fuel Pulse Damper 40-70 PSI

The AEM AN6 ORB Fuel Pulse Damper smooths the pressure pulsations created by injectors opening and closing and by fuel pump operation under load, working in tandem with your AEM fuel pressure regulator for steadier, more consistent fuel delivery. Ideal for setups running large injectors and high-volume fuel pumps.

Machined from full billet aluminum with stainless steel springs and a fluorosilicone diaphragm, it is compatible with any fuel and includes a 1/8in NPT port for a mechanical gauge or pressure transducer. Mounting fittings are included.
