Radium Early Nissan Walbro F90000267/274/285 Fuel Hanger - Pumps Not Included - 20-0732-00

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.

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.

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.

• Walbro F90000267 E85 -Not available pre-installed.
• Walbro F90000274 E85 -Available pre-installed.
• Walbro F90000285 E85 -Not available pre-installed.
• Walbro GSS342 255lph -Available pre-installed.
• AEM 50-1200 E85 -Available pre-installed.

If a "Pumps Not Included" option is selected, the kit will have enough parts to run 1, 2, or 3 fuel pumps but the user must supply their own compatible fuel pumps. Some assembly required.
P/N: 20-0732-00 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.
Adapter fittings are included for easy connection to the factory fuel lines.

P/N: 20-0730-00 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.

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 ETFE.

Notes:

• Single Walbro GSS342 (255LPH) fuel pump installations can re-use the OEM fuel pump wiring.
• It is recommended to upgrade OEM wiring to ensure the pumps are receiving full power and operating at their full potential.
• Select one for each aftermarket pump.

Features:

• Drop-In Installation
• Anodized Aluminum Construction
• Merged 8AN ORB Female Pump-Out Port
• Barbs and 6AN/8AN Fittings Included
• 8AN ORB Female Return Port
• Permits 1-3 Aftermarket Pumps
• Compatible with Various Pumps
• High Current Electrical Hardware
• Stainless Steel Hardware and Clamps
• Gasoline, Methanol, and E85 Compliant

This product is to be used with one of the fuel hangers above. It is recommended to use a single pump hanger to feed the surge tank. The surge tank can then be equipped with one or two fuel pumps to feed the engine.

The Radium Engineering FHST (fuel hanger surge tank) add-on is the ultimate solution for fuel starvation issues. Due to the saddle-bag style OEM fuel tank and insufficient baffling in late model Nissans, fuel slosh is common when driven aggressively. Unstable pressure resulting in a lean fuel mixture can cause engine damage. A stand-alone surge tank is an excellent device for eliminating fuel starvation issues, but installation can be complex. This add-on is a fully functional fuel surge tank mounted inside the OEM tank.

Simple plug and play connections are all that is required to attach the 2 systems together.

The surge tank can hold 1 or 2 aftermarket pumps including brushless variations. With the addition of the fuel pump in the OEM location, there could be 2-3 pumps inside the gas tank (total). Even with all of the extra fuel pumps, the FHST system is very straight forward and relatively simple to install.

No grinding, bending, or modification of the vehicle is required. Furthermore, the system is compatible with all alternative fuels such as E85.

What keeps the surge tank full?
The surge tank fuel pump(s) are supplied with fuel from 4 different sources:

• The high flow (low pressure) fuel pump located in the OEM location.
• The fuel returning from the fuel pressure regulator (FPR).
• The fuel transfer from the integrated venturi jet pump siphon.
• The 355LPH one-way fill valve on the bottom of the surge tank.

Electrical
External high current fuel pump wiring is provided for installing one FHST pump (1 relay, 1 fuse, and all associated wiring and hardware). To wire in a second FHST pump, a second fuse and relay are required. Consider purchasing Radium 17-0031 DIY Wiring Kit

Note:
Pumps Not Included

Because the fuel pump supplying the FHST (in the original pump location) will now operate at very low pressure (high flow), the OEM external fuel pump wiring will be sufficient for this "lift" pump.
