Full Description:
The Radium fuel pump hanger allows the use of 1 or 2 aftermarket pumps in the stock fuel tank. This item is NOT a fuel surge tank. The Radium fuel pump hanger has been designed and optimized for use with high horsepower systems. AN fittings allow the use of aftermarket high flow hose and the venturi jet pump is specially designed for high flow applications.

The machined assembly mounts in the factory fuel tank using the OEM hold-down flange and gasket. The OEM fuel level sender and temperature sensor (if equipped) are retained. Four -6AN male fittings (2 pump outlets, 1 return, 1 crossover) allow connection of aftermarket -AN hose.

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 cover plate. Nylon acorn nuts are provided to prevent any accidental short circuits. Furthermore, the high quality in-tank wiring is insulated with chemically resistant PTFE.

Crimp-on ring terminals and heat shrink are provided for external wiring connections.

The kit includes a venturi jet pump with a new integrated pressure relief valve. Without a properly designed jet pump, fuel cannot be properly transferred from the passive side of the OEM saddle bag fuel tank to the active side where the pump(s) reside. When fuel pump flow is increased, the OEM jet pump becomes too restrictive creating unwanted back-pressure in the FPR return line causing excessive fuel rail pressure.

The kit also includes an anodized aluminum collector box which improves the fuel supply around the pump(s) inlet. There is a 1" check valve incorporated on the front side of the tank that serves as a trap door keeping the pump(s) supplied with fuel during aggressive driving. Furthermore, all returning fuel from the pressure regulator return and the crossover hose enter the collector box through a one-way duckbill valve keeping it full. The duckbill valve prevents back flow and reduces noise from fuel spray. The collector box also permits a mounting solution for the OEM fuel level sender. This new revision simplifies installation and permits the hanger to be simply dropped into the tank in 1-piece.

Single pump applications can reuse the OEM fuel pump controller wiring, but it is recommended to upgrade the OEM wiring as high flow fuel pumps draw additional current requiring larger gauge wire. Purchase 1 kit for single pump applications and 2 for dual pump applications.

All Fuel Pump Hangers Feature:
• Billet Aluminum Top Plate Anodized & Laser Engraved
• Fully Enclosed Collector Box with One-Way Check Valve
• Electrical Terminals for the Wire Connections
• Stainless Steel Hardware
• AN Fuel Line Connections
• Submersible Fuel Hose See more Radium Products
