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.

Radium Engineering high-flow fuel filters are a perfect match for any application needing high flow and industry-leading filtration. Radium uses one of the largest filtration elements in the industry. This translates into a long service life and minimum flow loss, making the filters ideal for high-horsepower vehicles. The filters can be completely disassembled for servicing and replacement elements are available. Stainless steel mesh elements can be cleaned and re-used, while the Microglass element must be replaced at the end of its service life. The filters are designed for EFI fuel pressures and can be safely used on a high-pressure fuel feed line. The fuel filters are constructed with a 3-piece body that's CNC-machined from 6061 aluminum and Type-II anodized for maximum corrosion resistance. The end caps are sealed to the body with FKM O-rings. Both removable end caps feature large -10 AN ORB female threaded ports for high flow plumbing. Radium offers a large selection of adapter fittings to connect up to a variety of fuel hose types and sizes. These fuel filters come preassembled with the chosen filter element—and are compatible with all fuel types, including gasoline, diesel, methanol, ethanol, and alcohol blends such as E85. Choose the element material and micron filtration options preferred.

Radium Engineering fuel pump hangers permit the use of one, two, or three aftermarket pumps in the stock MK4 Toyota Supra (JZA80) fuel tank. Features include: * Drop-in OEM replacement * 8 AN male pump outlet * 6 AN male return inlet * Fuel starvation protection * High current electrical hardware * Compatible with various pumps (Walbro, AEM, etc.) * Anodized aluminum construction To simplifying aftermarket -AN hose plumbing, the 10 AN ORB threaded feed port features a low-profile 8 AN male fitting, and the 8 AN ORB threaded return port features a low-profile 6 AN male fitting. To reconnect the OEM return and vent hoses, 8.5mm barb fittings are also included. No permanent modification to the OEM fuel tank access cover is required. The custom designed stainless electrical studs easily handle the high current demand that compact bulkhead connectors lack. These serviceable connections are properly sealed and impervious to all standard and exotic fuels. The low-profile design keeps all wiring tucked nicely underneath the OEM fuel tank cover using the provided foam insulation. Nonconductive acorn nuts are provided to prevent any accidental short circuits. The high quality in-tank wiring is insulated with chemically resistant ETFE. Electrical hardware is included for the fuel pump(s), OEM level sender, and OEM temperature sensor. One issue with all Supra fuel pump hangers is the lack of fuel starvation protection. In these kits, the flow from the FPR return line powers a Radium jet pump. Using a venturi-effect, this "mechanical" pump draws fuel from outside the sub-tank and distributes it directly to the pump inlets.

The opening and closing of fuel injectors create pressure pulses in the fuel rail which can lead to unstable fuel pressure. 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
