The Radium Engineering fuel pump hanger replaces the entire factory assembly. It can be configured with 1 or 2 aftermarket fuel pumps to meet the fuel demands of various high performance engines. Fuel pump options include Walbro (Ti Automotive) or AEM.

The functionality of the factory Nissan level sender, low fuel switch, and fuel temperature (OBD-II only) are retained. Adapter fittings are provided that permit direct connections for all factory fuel line variations (quick connect and hose barb). No extra fuel plumbing is required. As shown below, the adapter fittings can be changed for -AN style hoses as well (sold separately).

The OEM system uses a venturi jet pump to transfer fuel from the passive side of the tank to the active (pump) side of the tank. When using aftermarket high-flow pumps this venturi jet pump creates a restriction in the fuel return, resulting in unwanted backpressure and unmanageable fuel pressure. Radium Engineering has redesigned the siphon system to completely eliminate this restriction but still effectively scavenge fuel the same as factory. 
1. Depending on fuel pressure, the venturi jet pump will consume 15-45 LPH. Take this fuel loss into consideration when sizing the fuel pumps.
2. If it is important for fuel pressure to hold steady after the engine is shut down, install one of these CHECK VALVES somewhere in the fuel system.

All kits come partially assembled with the final assembly performed by the technician during installation. Refer to the instructions above for more details.

If a "Pumps Not Included" option is selected, the kit will have enough parts to run 1 or 2 fuel pumps and the user must supply their own compatible fuel pumps.

If a "Pumps Included" option is selected, the kit will include the fuel pump(s) and corresponding sock filter(s). NOTE: When the unit is purchased with one pump included, additional parts will be needed to install a second pump. 

This system supports the following fuel pumps:
Walbro F90000267 E85
Walbro F90000274 E85
Walbro F90000285 E85
Walbro GSS342 255lph
AEM 50-1200 E85
Ti Automotive E5LM (brushless)

The custom designed stainless steel electrical studs easily handle the high current demand that compact multi-pin bulkhead connectors lack. These serviceable connections are hermetically sealed and impervious to all standard and exotic fuels. Non-conductive anodized aluminum acorn nuts are provided to prevent any accidental short circuiting. Enough studs are built in the top hat to accomodate brushless fuel pumps as well as the FHST add-on, described below.

Electrical hardware is included for the fuel pump(s) and sensors. Furthermore, the in-tank wiring is insulated with high quality chemically resistant PTFE. 

1. Single fuel pump installations can re-use the OEM fuel pump controller wiring.
2. It is recommended to upgrade OEM wiring to ensure the pumps are receiving full power and operating at their full potential.
3. Universal fuel pump wiring kits can be found HERE. Select one for each aftermarket pump.
