Radium Fuel Hanger Late Nissan S14 R33 R34 Pumps Not Included

The Radium Engineering fuel pump hanger replaces the entire factory fuel pump assembly inside the Nissan fuel tank. 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 pump(s) are suspended down in the bottom of the tank, similar to the stock fuel hanger. From there, they feed through polyamide nylon tubing to the top hat. 

The factory Nissan fuel level sender, low fuel switch, and fuel temperature (OBD-II only) are reused so full functionality is retained.
A venturi jet pump is integrated into the top plate and provides means to draw fuel from the opposite side of the fuel tank.

FITTINGS

The threads on the feed port are 10AN ORB (7/8"-14). The threads on the return port are 8AN ORB (3/4"-16). The pre-installed adapter fittings permit direct connections for all factory fuel line variations (SAE quick connect and hose barb). No extra fuel plumbing is required if using stock fuel lines. If using aftermarket -AN style hoses, low profile -AN swivel adapter fittings will be required and are sold separately. 
(Note: Straight adapter fittings may also be used, but clearance with the access cover plate will not be possible)


The photo below shows -AN swivel adapters installed in the feed and return ports. The crossover port (center) does not need to be changed.


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. 
NOTES: 
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 a check valvesomewhere in the fuel system.

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)

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. 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 ETFE. 

Notes
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.
