![]() ![]() Furthermore, the high quality in-tank wiring is insulated with chemically resistant PTFE. Nylon acorn nuts are provided to prevent any accidental short circuits. The low profile design keeps all wiring tucked nicely underneath the OEM cover plate. ![]() These serviceable connections are properly sealed and impervious to all standard and exotic fuels. The custom designed stainless electrical studs easily handles the high current demand that compact bulkhead connectors lack. Electrical hardware is included for the fuel pump power, OEM level sender, and OEM temperature sensor. A single 8AN male pump feed port and 6AN male return port simplify aftermarket -AN hose plumbing. The machined assembly drops-in the factory fuel tank using the OEM hold-down flange. This valve maintains fuel pressure after the engine is shut down.The Radium Engineering fuel pump hanger allows the use of 1 or 2 aftermarket pumps in the stock Mitsubishi Evo X fuel tank. Furthermore, there is a new high flow integrated check valve on the merged fuel pump outlet, as shown above. Take this fuel loss into consideration when sizing the fuel pump(s).ģ. The new venturi jet pump will consume 15-45 LPH, depending on the current fuel pressure. This means higher flowing pumps can be safely used without inducing fuel pressure issues.Ģ. The siphon system has been redesigned to completely eliminate any restriction on the return line but still effectively scavenge fuel. Using a venturi-effect, this “mechanical” pump draws fuel from outside the sub-tank and distributes it directly to the pump inlets.Īs shown, the sub-tank stays full in all driving conditions.ġ. The Radium Engineering system incorporates a unique siphon jet pump. One conclusion with the dated OEM system is poor protection against fuel starvation. ![]() Select qty1 for single pump applications, qty2 for dual pump applications, and qt圓 for triple pump applications. Fuel pump wiring kits can be purchased HERE. Single pump applications can reuse the OEM fuel pump controller wiring, but it is recommended to upgrade the OEM wiring as these high flow fuel pumps draw additional current requiring larger gauge wire. Electrical hardware is included for the fuel pump(s), OEM level sender, and OEM temperature sensor. Furthermore, the high quality in-tank wiring is insulated with chemically resistant ETFE. Nonconductive acorn nuts are provided to prevent any accidental short circuits. The low profile design keeps all wiring tucked nicely underneath the OEM fuel tank cover using the provided foam insulation. To reconnect the OEM return and vent hoses, barb fittings are also included.Īs shown below, the custom designed stainless electrical studs easily handle the high current demand that compact bulkhead connectors lack. To simplifying aftermarket -AN hose plumbing, the 10AN ORB threaded feed port (depicted below) features a low profile 8AN male fitting and the 8AN ORB threaded return port features a low profile 6AN male fitting.īecause the fuel pumps utilize integrated check valves, the pump outlets merge into a single 10AN billet collector (20-1511 includes check valves for pump outlets). no permanent fuel access cover modifications are required. The Radium Engineering fuel pump hanger permits the use of 1, 2, or 3 aftermarket pumps in the stock MK4 Toyota Supra (JZA80) fuel tank. Instructions for older 20-041X-XX and 20-051X-XX (these kits have been discontinued) ![]()
