Description: Radium Early Nissan Walbro GS342 or AEM 50-1200 Fuel Hanger - Pumps Not Included

Fitment: 89-94 Nissan Skyline R32 GTST RB20DET

Details:

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.

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 one of these CHECK VALVES somewhere in the fuel system.

This system supports the following fuel pumps:
Walbro F90000267 E85
Walbro F90000274 E85
Walbro F90000285 E85
Walbro GSS342 255lph
