Radium Engineering offers top feed fuel rail conversion kits for specific applications. Manufactured with a large 0.69 in. internal bore, the fuel rails can support all necessary engine power requirements. They are CNC-machined from a custom 6063 aluminum, media blasted, black anodized, and laser-etched for a high-quality surface finish. These kits are compatible with all fuel types, including popular alcohol mixtures such as E85. The Radium fuel rail converts the OEM side feed fuel injector setup to top feed, allowing the use of high-flow fuel injectors (not included). Each kit includes two different sets of mounting feet, allowing various height fuel injectors to be used. The anodized aluminum mounting feet secure the fuel rail to the intake manifold reusing the OEM thermal insulating spacers. The fuel injector bores and the included press-fit injector seats are designed for 14mm injector O-rings. These seats include O-rings to prevent boost pressure leaks. They're CNC-machined billet aluminum, anodized, and laser etched.

DeatschWerks top-feed conversion fuel rails are designed to convert side-feed applications to top-feed. Many performance vehicles manufactured between 1991 and 2006 came from the factory with side-feed injectors. The benefit of the modern top-feed injectors is that they are easier to tune, less expensive, and flow more fuel than side-feed alternatives. These vehicle-specific fuel rails are sold in pairs. DW also offers upgrade conversion kits that come with injectors ranging from 750cc to 2200cc and are engineered as a system where injector, rails, and mounting hardware that work together to integrate flawlessly into the OE manifold and mounting points. Select the fuel rails or the upgrade conversion kit recommended for your application.

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
