OVERVIEW
This Radium Engineering fuel pump hanger replaces the stock fuel pump module in the Nissan vehicles listed above. It can be configured with 1, 2, or 3 aftermarket fuel pumps to meet the fuel demands of various high performance engines. No cutting or modifying of the vehicle's sheet metal or fuel tank is required for installation.
The fuel pumps are positioned in the factory collector bowl. Fuel is drawn in through the mesh filter located at the bottom of the assembly, shown below.

The functionality of the factory Nissan fuel level float and low fuel switch are retained. 

The fuel pump outlets merge into a single 8AN female port on the top plate. And because of the integrated check valves, fuel pump staging is permitted. The return port also uses a 8AN ORB female port on the top plate.

 

Adapter fittings are included for easy connection to the factory fuel lines.

Also included in all variations of the kit are adapter fittings for connecting aftermarket -AN style hoses. The fitting ports are machined low enough to clear the unibody sheet metal.


FUEL PUMP CONFIGURATION
There are many different combinations of fuel pumps available described below. Choosing the pump(s) is based on the expected engine power output and the fuel type (gasoline, E85, etc.). Use the information below to help make your selection.

P/N: 20-0732-00

(shown below) can be used with the Walbro F9000267, Walbro F90000274 or Walbro F90000285 pumps.



P/N: 20-0730-00 (shown below) can be used with the AEM 50-1000, AEM 50-1200, Walbro GSS342, or other pumps with the same physical shape and electrical connector



If a "Pumps Included" option is selected, the kit will be preassembled with fuel pump(s) and ready to drop into the fuel tank. An example is shown below.

NOTE: If less than 3 pumps are pre-installed in the asembly, additional parts will be needed to install extra pumps. 


ELECTRICAL

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.

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

Notes
1. Single Walbro GSS342 (255LPH) fuel pump installations can re-use the OEM fuel pump 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.
