Radium Engineering Fuel Pulse Dampers

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

Radium Engineering Fuel Surge Tanks

Radium Engineering offers fuel surge tanks in a variety of styles—including with two or three fuel pumps, and for gasoline and/or flex fuel. A fuel surge tank (FST) is designed to prevent fuel starvation to the engine on vehicles with inadequate fuel tank baffling. Fuel is supplied to the surge tank by a lift pump, which in most cases is the OEM in-tank fuel pump. The volume of fuel inside the surge tank acts as a buffer to always keep the FST pump(s) supplied with fuel, even if the lift pump starves momentarily. This volume is maintained by the lift pump as well as the fuel returning from the fuel pressure regulator. Excess fuel in the surge tank is returned back to the vehicle's main fuel tank. The surge tank also provides a quick and easy way to upgrade any standard fuel system without opening the stock fuel tank. This is an excellent fueling solution for vehicles installing large demand power upgrades such as forced induction.
