Radium Engineering's Venturi jet pump kits are designed for high-flow aftermarket pumps and includes three different Venturi orifices to match a wide range of pump flow rates. The Radium jet pump is an effective device for drawing fuel from one side of a fuel tank to the other. Fuel flowing through the venturi creates vacuum in the perpendicular port. The Venturi jet pump uses a machined aluminum housing that is anodized, and laser engraved. Kit includes three interchangeable orifices that were precisely calculated, and vacuum pressure tested with multiple pump combinations. All hose barb connections are compatible with 5/16 in. or 3/8 in. ID hose. Also, the crossover siphon port can be easily adapted to common hoses as it uses 6AN ORB (9/16 in.-18 O-ring) female threads.

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
