Holley Fuel Pressure Regulators with Pulse Damper

Holley fuel pressure regulators with a pulse damper offer several benefits for performance and reliability. Fuel pulse dampers are designed to act in tandem with the fuel pressure regulator to further control the fuel pressure in an EFI system. These devices help stabilize fuel pressure by absorbing the pressure fluctuations (pulsations) caused by injectors opening and closing, and by the fuel pump. This leads to smoother fuel delivery, improved engine performance, and can help prevent lean spots that can cause stumbling or hesitation, especially during acceleration. 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/regulator's and direct mount dampers * 1/8 in. NPT port on body for easy installation of mechanical pressure gauge or pressure transducer/ * Vacuum fitting and one foot of hose included with all dampers for vacuum referencing
