Holley EFI 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. Options include: * Direct-mount or inline mount * Multiple inlet/outlet dimensions * Standard or extended fuel pressure range * Male or female threads 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 in. NPT port on body of damper/regulators and inline dampers for easy installation of mechanical pressure gauge or pressure transducer * Vacuum fitting and one foot of hose included with all dampers for vacuum referencing

The opening and closing of fuel injectors creates pressure pulses in the fuel rail which can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a Radium Engineering fuel pulse damper (FPD) is often necessary. The FPD's internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and often help idle surge, especially with high-flow injectors. A fuel pulse damper can also solve erratic lean air/fuel ratio spikes, commonly experienced as "stumbling," that are difficult to tune out. What makes Radium FPDs unique?: Along with having the flexibilty of using common fittings, Radium Engineering FPD's use a vacuum/boost reference port which allows for proper fuel pulse damper performance even at elevated fuel pressures. This becomes essential for boosted systems that use a 1:1 rising rate fuel pressure regulator. Features: The anodized aluminum housing features two selectable threaded male fittings. The 8 AN ORB version seals using a FKM O-ring, while the 3/8 in. NPT variation seals with the tapered pipe threads. * The FPDs can be mounted at any possible angle including upside down. For best results, the damper should be mounted directly onto the fuel rail(s). These products are safe for use with all fuel types, including alcohol blends such as E85. (Not recommended for the low-pressure side of mechanical fuel pumps.) Included: * Anodized and laser engraved aluminum top, R=range or XR=extra range * Anodized aluminum body with male threads, 8 AN ORB or 3/8 in. NPT * Stainless steel hardware * Rubber vacuum hose, 4mm I.D. * Vacuum hose Y-fitting

To achieve a safe and consistent rail pressure, a fuel pulse damper (FPD) is often necessary. Radium Engineering fuel system pulsation dampers feature an internal diaphragm that will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the rpm range and can often help idle surge, especially with high-flow injectors. They also help solve erratic lean air/fuel ratio spikes, commonly experienced as "stumbling", that are difficult to tune out. Kits come with different male adapter fittings. Choose the proper one for your fuel feed hose. Features: * Anodized aluminum housing with a large 0.69 in. center bore * Two in-line inlet/outlet ports machined with 3/4 in.-16 UNF threads for 8 AN ORB fittings * At 1.98 in. tall, the FPD-R can be used in space-constrained applications * FPD-R base pressure requirement equals 40 to 70 psi (static) * Includes adapter fittings which seal to the billet housing using Viton® O-rings * An 1/8 in. NPT female port is threaded into the center of the fuel pulse damper * Safe for use with all fuel types, including alcohol blends such as E85 * Vacuum/boost reference port allows for proper performance even at elevated fuel pressures

Fuel pulse dampers, or pulsation dampers, act in tandem with the fuel pressure regulator to ensure stable and consistent fuel delivery to the engine. They do this by smoothing out the pressure fluctuations, or pulsations, caused by the injectors opening and closing, as well as the fuel pump operating. AEM Electronics fuel pulse dampers feature billet aluminum construction with an anodized finish and are ideal for applications with large fuel injectors and high-volume fuel pumps. They are compatible with any fuel and available as a direct-mount or in-line style with a standard or extended psi range. Select the best fit for your fuel system.
