![]() ![]() ![]() Like any fuel system part, the FPD kit should be kept away from excessive heat areas.For best results, the damper should be plumbed as close to the fuel rail(s) as possible.Using the supplied M6 bolts/nuts, the FPD kit can be mounted at any possible angle including upside down.These fittings seal to the billet housing using Rubber O-rings.Depending on the size of the fuel feed hose used, there are 3 kits to choose from which include different male adapter fittings (-6AN, -8AN, -10AN).The kit features an anodized aluminum housing with a large 0.69" center bore that uses two in-line inlet/outlet ports that are machined with 3/4"-16 UNF threads for 8AN ORB fittings.Highly resistant to wear and tear, these parts will handle the toughest conditions offering long-lasting service. Designed using the latest computer simulation and modeling techniques, they will exceed your expectations in every way. Want to improve fuel delivery to squeeze extra power out of your engine? Choose from top-quality Radium performance fuel system parts. Furthermore, a fuel pulse damper can help solve erratic lean air/fuel ratio spikes, commonly experienced as "stumbling", that are difficult to tune out. ![]() This correction can be measured throughout the RPM range and can often help idle surge, especially with high flow injectors. The FPD's internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. In order to achieve a safe and consistent rail pressure, a fuel pulse damper (FPD) is often necessary. The opening and closing of fuel injectors creates pressure pulses in the fuel rail which can lead to unstable fuel pressure. This product IS NOT intended to be used directly on a fuel rail port.Range In-line Fuel Pulse Damper Kit by Radium®.The NPT fitting requires PTFE paste for proper sealing.When installing, the O-rings require petroleum oil for lubrication.1/8" NPT auxilary port for optional accessories (A plug is included if this will not be used).Large 10AN ORB inlet and outlet ports (6AN and 8AN adapters are included).Fuel Pulse Damper stabilizes fuel pressure created by the fuel pressure regulator, pump, injectors, etc.Fuel Pressure Regulator has been tested to regulate over 1,400 liters per hour.The FPR-D is compatible with all gasoline and alcohol blends of fuel including E85.Fully functional high performance pressure regulator with a unique built-in fuel pulse damper.The FPR-D can be mounted any direction including upside down. A laser cut anodized aluminum mounting plate with countersink M6x1mm bolts/nuts are included. The FPR-D assembly features two M6x1mm threaded mounting holes. A plug is included if this port will not be used. The 1/8" NPT auxilary port can be used for monitoring fuel pressure, temperature, etc. Two -6AN and two -8AN adapter fittings are included to suit most aftermarket fuel systems. The inlet (side) port and outlet (bottom) port feature large 10AN ORB (7/8"-14) threaded ports. Any dynamic fuel pressure created by the rising rate FPR outside of this range is acceptable assuming the vacuum/boost reference line is connected. The base pressure requirement for maximum damping efficiency is 40-120psi (2.8-8.3bar). Unlike many others, the stainless steel adjustament screw has super fine threads for resisting vacuum/boost leaks and fine tuning fuel pressure.įuel Pulse Damper: The integrated 1:1 fuel pulse damper stabilizes fuel pressure created by the fuel pressure regulator, fuel pump, fuel injectors, etc. Fuel pressure is dialed in using the preload set screw on top. Furthermore, with the addition of interchangeable return orifices, the regulator is a good match for big to small powered engines. This added precision will resist diaphragm flutter and optimize pressure stability. Two interchangeable orifices are included to match the amount of fuel bypassed for the application. The FPR-D is compatible with all gasoline and alcohol blends of fuel including E85.įuel Pressure Regulator: The 1:1 vacuum reference high flow design has been tested to regulate over 1,400 liters per hour. It is a fully functional high performance pressure regulator with a unique built-in fuel pulse damper, an industry first. The Fuel Pressure Regulator-Damper (FPR-D) is the ultimate solution for consolidating critical fuel system components into a high-flow package.
