Radium fuel pump hangers upgrade#

Note: 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.

Electrical terminals for the wire connections.

Fully enclosed collector box with one-way check valve.

Billet aluminum top plate, anodized and laser engraved.

Dual Pumps Included – Select this option for a fully assembled hanger with both pumps preinstalled.

Parts to add a second pump are NOT included with this setup. It will come pre-assembled with the pump installed. Single Pump Included – Select this option if you wish to only run a single pump in the hanger.To ensure proper parts included, make sure the correct hanger is selected for the model of pump you have.

Enough parts are included to install one or two pumps. No Pre-installed pumps – Select this option if you already have compatible fuel pumps and wish to install them into the hanger.The 2015+ WRX requires Radium 20-0350 Fuel Level Sender Adapter.Īvailable Fuel Pump Hanger Configurations: The collector box also permits a mounting solution for the OEM fuel level sender. The duckbill valve prevents back flow and reduces noise from fuel spray. 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. There is a 1″ check valve incorporated on the front side of the tank that serves as a trap door that allows fuel in but not out of the collector box. The anodized aluminum collector box keeps fuel trapped around the pumps, helping to prevent fuel starvation.

The unique design of the Radium jet pump creates suction while not providing too much restriction in fuel return line. When fuel pump flow is increased, the OEM jet pump becomes too restrictive creating unwanted backpressure in the FPR return line causing excessive fuel rail pressure.

This device transfers fuel from the passive side of the OEM fuel tank to the active side where the pump(s) reside. The kit includes a venturi jet pump integrated within the collector box that features a new integrated pressure relief valve. Crimp-on ring terminals and heat shrink are provided for external wiring connections. Nonconductive 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 hermetically sealed and impervious to all standard and exotic fuels. Unlike compact multi-pin electrical connectors, the custom designed stainless steel electrical studs easily handle the high current demand from aftermarket fuel pumps. The OEM fuel level sender and temperature sensor (if equipped) are retained. The machined assembly mounts in the factory fuel tank using the OEM hold-down flange and gasket. The system is safe to use with alternative fuels such as E85.

The return fuel and crossover fittings are also 6AN male. Each fuel pump has it’s own dedicated 6AN male outlet, which can be combined together into single feed line with the use of a “Y” fitting, or with one of the plumbing kit options on this page. No permanent modifications to the vehicle are required making installation a simple bolt-on job. The Radium fuel pump hanger for the late model Subaru vehicles replaces the stock in-tank hanger and allows the use of 1 or 2 high-flow aftermarket fuel pumps in the stock fuel tank.
